  -----------------------------------------
  
  An on-screen virtual keyboard embedded within the browser window which
  will popup when a specified entry field is focused. The user can then
  type and preview their input before Accepting or Canceling.
  
  As a plugin to jQuery UI styling and theme will automatically
  match that used by jQuery UI with the exception of the required
  CSS listed below.
  
  Requires:
  	jQuery
  	jQuery UI (position utility only) & CSS
  
  Usage:
  	$('input[type=text], input[type=password], textarea')
  		.keyboard({
  			layout:"qwerty",
  			customLayout: {
  				'default': [
  					"q w e r t y {bksp}",
  					"s a m p l e {shift}",
  					"{accept} {space} {cancel}"
  				],
  				'shift' : [
  					"Q W E R T Y {bksp}",
  					"S A M P L E {shift}",
  					"{accept} {space} {cancel}"
  				]
  			}
  		});
  
  Options:
  	layout
  		[String] specify which keyboard layout to use
  		qwerty - Standard QWERTY layout (Default)
  		international - US international layout
  		alpha  - Alphabetical layout
  		dvorak - Dvorak Simplified layout
  		num    - Numerical (ten-key) layout
  		custom - Uses a custom layout as defined by the customLayout option
  
  	customLayout
  		[Object] Specify a custom layout
  			An Object containing a set of key:value pairs, each key is a keyset.
  			The key can be one to four rows (default, shifted, alt and alt-shift) or any number of meta key sets (meta1, meta2, etc).
  			The value is an array with string elements of which each defines a new keyboard row.
  			Each string element must have each character or key seperated by a space.
  			To include an action key, select the desired one from the list below, or define your own by adding it to the $.keyboard.keyaction variable
  			In the list below where two special/"Action" keys are shown, both keys have the same action but different appearances (abbreviated/full name keys).
  			Special/"Action" keys include:
  				{a}, {accept} - Updates element value and closes keyboard
  				{alt},{altgr} - AltGr for International keyboard
  				{b}, {bksp}   - Backspace
  				{c}, {cancel} - Clears changes and closes keyboard
  				{clear}       - Clear input window - used in num pad
  				{combo}       - Toggle combo (diacritic) key
  				{dec}         - Decimal for numeric entry, only allows one decimal (optional use in num pad)
  				{default}     - Switch to the default keyset
  				{e}, {enter}  - Return/New Line
  				{empty}       - empty (blank) key
  				{lock}        - Caps lock key
  				{meta#}       - Meta keys that change the key set (# can be any integer)
  				{next}        - Switch to next keyboard input/textarea
  				{prev}        - Switch to previous keyboard input/textarea
  				{s}, {shift}  - Shift
  				{sign}        - Change sign of numeric entry (positive or negative)
  				{sp:#}        - Replace # with a numerical value, adds blank space, value of 1 ~ width of one key
  				{space}       - Spacebar
  				{t}, {tab}    - Tab

  	Please see the keyboard.css file

   * jQuery UI Virtual Keyboard Typing Simulator v1.3 for Keyboard v1.8.14+ only
   *
   * By Rob Garrison (aka Mottie & Fudgey)
   * Licensed under the MIT License
   *
   * Use this extension with the Virtual Keyboard to simulate
   * typing for tutorials or whatever else use you can find
   *
   * Requires:
   *  jQuery
   *  Keyboard plugin : https://github.com/Mottie/Keyboard
   *
   * Setup:
   *  $('.ui-keyboard-input')
   *   .keyboard(options)
   *   .addTyping(typing-options);
   *
   *  // or if targeting a specific keyboard
   *  $('#keyboard1')
   *   .keyboard(options)
   *   .addTyping(typing-options);
   *
   * Basic Usage:
   *  // To disable manual typing on the virtual keyboard, just set "showTyping" option to false
   *  $('#keyboard-input').keyboard(options).addTyping({ showTyping: false });
   *
   *  // Change the default typing delay (time the virtual keyboard highlights the manually typed key) - default = 250 milliseconds
   *  $('#keyboard-input').keyboard(options).addTyping({ delay: 500 });
   *
   *  // get keyboard object, open it, then start typing simulation
   *  $('#keyboard-input').getkeyboard().reveal().typeIn('Hello World', 700);
   *
   *  // get keyboard object, open it, type in "This is a test" with 700ms delay between types, then accept & close the keyboard
   *  $('#keyboard-input').getkeyboard().reveal().typeIn('This is a test', 700, function(){ $('#keyboard-input').getkeyboard().close(true); });
   */
