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

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