/**
* ProxyStore is a superclass of {@link Ext.data.Store} and {@link Ext.data.BufferedStore}. It's never used directly,
* but offers a set of methods used by both of those subclasses.
*
* We've left it here in the docs for reference purposes, but unless you need to make a whole new type of Store, what
* you're probably looking for is {@link Ext.data.Store}. If you're still interested, here's a brief description of what
* ProxyStore is and is not.
*
* ProxyStore provides the basic configuration for anything that can be considered a Store. It expects to be
* given a {@link Ext.data.Model Model} that represents the type of data in the Store. It also expects to be given a
* {@link Ext.data.proxy.Proxy Proxy} that handles the loading of data into the Store.
*
* ProxyStore provides a few helpful methods such as {@link #method-load} and {@link #sync}, which load and save data
* respectively, passing the requests through the configured {@link #proxy}.
*
* Built-in Store subclasses add extra behavior to each of these functions. Note also that each ProxyStore subclass
* has its own way of storing data - in {@link Ext.data.Store} the data is saved as a flat {@link Ext.util.Collection Collection},
* whereas in {@link Ext.data.BufferedStore BufferedStore} we use a {@link Ext.data.PageMap} to maintain a client side cache of pages of records.
*
* The store provides filtering and sorting support. This sorting/filtering can happen on the client side
* or can be completed on the server. This is controlled by the {@link Ext.data.Store#remoteSort remoteSort} and
* {@link Ext.data.Store#remoteFilter remoteFilter} config options. For more information see the {@link #method-sort} and
* {@link Ext.data.Store#filter filter} methods.

* Reloads the store using the last options passed to the {@link #method-load} method. You can use the reload method to reload the

* store.load({
* params : {
* userid : 22216
* }
* });
*
* //...
*
* store.reload();
*
* The initial {@link #method-load} execution will pass the `userid` parameter in the request. The {@link #reload} execution
* will also send the same `userid` parameter in its request as it will reuse the `params` object from the last {@link #method-load} call.
*
* You can override a param by passing in the config object with the `params` object:
*
* store.load({
* params : {
* userid : 22216,
* foo : 'bar'
* }
* });
*
* //...
*
* store.reload({
* params : {
* userid : 1234
* }
* });
*
* The initial {@link #method-load} execution sends the `userid` and `foo` parameters but in the {@link #reload} it only sends
* the `userid` paramter because you are overriding the `params` config not just overriding the one param. To only change a single param
* but keep other params, you will have to get the last params from the {@link #lastOptions} property:
*
* var lastOptions = store.lastOptions,
* lastParams = Ext.clone(lastOptions.params); // make a copy of the last params so we don't affect future reload() calls
*
* lastParams.userid = 1234;
*
* store.reload({
* params : lastParams
* });
*
* This will now send the `userid` parameter as `1234` and the `foo` param as `'bar'`.
*

* and functions can be chained together. Methods that retrieve a single value
* or may return a primitive value will automatically end the chain sequence
* and return the unwrapped value. Otherwise, the value must be unwrapped
* with `_#value`.
*
* Explicit chain sequences, which must be unwrapped with `_#value`, may be
* enabled using `_.chain`.
*
* The execution of chained methods is lazy, that is, it's deferred until
* `_#value` is implicitly or explicitly called.
*
* Lazy evaluation allows several methods to support shortcut fusion.
* Shortcut fusion is an optimization to merge iteratee calls; this avoids
* the creation of intermediate arrays and can greatly reduce the number of
* iteratee executions. Sections of a chain sequence qualify for shortcut
* fusion if the section is applied to an array and iteratees accept only
* one argument. The heuristic for whether a section qualifies for shortcut
* fusion is subject to change.
*
* Chaining is supported in custom builds as long as the `_#value` method is
* directly or indirectly included in the build.
*
* In addition to lodash methods, wrappers have `Array` and `String` methods.
*
* The wrapper `Array` methods are:
* `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
*
* The wrapper `String` methods are:
* `replace` and `split`
*
* The wrapper methods that support shortcut fusion are:
* `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
* `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
* `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
*
* The chainable wrapper methods are:
* `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
* `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,
* `commit`, `compact`, `concat`, `conforms`, `constant`, `countBy`, `create`,
* `curry`, `debounce`, `defaults`, `defaultsDeep`, `defer`, `delay`,
* `difference`, `differenceBy`, `differenceWith`, `drop`, `dropRight`,
* `dropRightWhile`, `dropWhile`, `extend`, `extendWith`, `fill`, `filter`,
* `flatMap`, `flatMapDeep`, `flatMapDepth`, `flatten`, `flattenDeep`,
* `flattenDepth`, `flip`, `flow`, `flowRight`, `fromPairs`, `functions`,
* `functionsIn`, `groupBy`, `initial`, `intersection`, `intersectionBy`,
* `intersectionWith`, `invert`, `invertBy`, `invokeMap`, `iteratee`, `keyBy`,
* `keys`, `keysIn`, `map`, `mapKeys`, `mapValues`, `matches`, `matchesProperty`,
* `memoize`, `merge`, `mergeWith`, `method`, `methodOf`, `mixin`, `negate`,
* `nthArg`, `omit`, `omitBy`, `once`, `orderBy`, `over`, `overArgs`,

* `valuesIn`, `without`, `wrap`, `xor`, `xorBy`, `xorWith`, `zip`,
* `zipObject`, `zipObjectDeep`, and `zipWith`
*
* The wrapper methods that are **not** chainable by default are:

* `cloneDeep`, `cloneDeepWith`, `cloneWith`, `conformsTo`, `deburr`,

* Creates a debounced function that delays invoking `func` until after `wait`
* milliseconds have elapsed since the last time the debounced function was
* invoked. The debounced function comes with a `cancel` method to cancel
* delayed `func` invocations and a `flush` method to immediately invoke them.
* Provide `options` to indicate whether `func` should be invoked on the
* leading and/or trailing edge of the `wait` timeout. The `func` is invoked
* with the last arguments provided to the debounced function. Subsequent

* invocation.
*
* **Note:** If `leading` and `trailing` options are `true`, `func` is
* invoked on the trailing edge of the timeout only if the debounced function
* is invoked more than once during the `wait` timeout.
*
* If `wait` is `0` and `leading` is `false`, `func` invocation is deferred

* actions in a convenient way. Asynchronous middleware like redux-thunk or
* redux-promise wraps the store's dispatch() method and allows you to dispatch
* something other than actions, for example, functions or Promises. Any
* middleware you use can then interpret anything you dispatch, and in turn, can
* pass actions to the next middleware in the chain. For example, a Promise
* middleware can intercept Promises and dispatch a pair of begin/end actions
* asynchronously in response to each Promise. When the last middleware in the
* chain dispatches an action, it has to be a plain object. This is when the
* synchronous Redux data flow takes place. */
