; /**
  * AngularJS directive that simulates the effect of typing on a text editor - with a blinking cursor.
  * This directive works as an attribute to any HTML element, and it changes the speed/delay of its animation.
  *
  * There's also a simple less file included for basic styling of the dialog, which can be overridden.
  * The config object also lets the user define custom CSS classes for the modal.
  *
  *  How to use:
  *
  *  Just add the desired text to the 'text' attribute of the element and the directive takes care of the rest.
  *  The 'text' attribute can be a single string or an array of string. In case an array is passed, the string
  *  on each index is erased so the next item can be printed. When the last index is reached, that string stays
  *  on the screen. (So if you want to erase the last string, just push an empty string to the end of the array)
  *
  * These are the optional preferences:
  *  - initial delay: set an 'initial-delay' attribute for the element
  *  - type delay: set a 'type-delay' attribute for the element
  *  - erase delay: set a 'erase-delay' attribute for the element
  *  - specify cursor : set a 'cursor' attribute for the element, specifying which cursor to use
  *  - turn off cursor blinking: set the 'blink-cursor' attribute  to "false"
  *  - cursor blinking speed: set a 'blink-delay' attribute for the element
  *  - scope callback: pass the desired scope callback as the 'callback-fn' attribute of the element
  *
  * Note:
  * Each time/delay value should be set either on seconds (1s) or milliseconds (1000)
  *
  * Dependencies:
  * The directive needs the css file provided in order to replicate the cursor blinking effect.
