  We will produce two compiler entry-points, `ngtsc` and `ngcc`.
  -`ngtsc` will be an Typescript-to-Javascript transpiler that reifies Angular decorators into static properties. It is a minimal wrapper around `tsc` which includes a set of Angular transforms. While Ivy is experimental, `ngc` operates as `ngtsc` when the `angularCompilerOption` `enableIvy` flag is set to `true` in the `tsconfig.json` file for the project.

While Ivy is experimental, `ngc` operates as `ngtsc` when the `angularCompilerOption` `enableIvy` flag is set to `true` in the `tsconfig.json` file for the project.
  `ngcc` (which stands for Angular compatibility compiler) is designed to process code coming from NPM and produce the equivalent Ivy version, as if the code was compiled with `ngtsc`. It will operate given a `node_modules` directory and a set of packages to compile, and will produce an equivalent directory from which the Ivy equivalents of those modules can be read. `ngcc` is a separate script entry point to `@angular/compiler-cli`.

  ##### Finding a components module.
  -A component's module can be found by using the TypeScript language service's `findReferences`. If one of the references is to a class declaration with an `@NgModule` annotation, process the class as described above to produce the selector scope.

  +A component's module can be found by using the TypeScript language service's `findReferences`. If one of the references is to a class declaration with an `@NgModule` annotation, process the class as described above to produce the selector scope. If the class is the declaration list of the `@NgModule` then use the scope produced for that module.
  When processing the `@NgModule` class, the type references can be found using the program's `checker` `getSymbolAtLocation` (potentially calling `getAliasedSymbol` if it is an alias symbol, `SymbolFlags.Alias`) and then using `Symbol`'s `declarations` field to get the list of declarations nodes (there should only be one for a `class`, there can be several for an `interface`).
