/**
* @ngdoc directive
* @name ng.directive:ngClass
*
* @description
* The `ngClass` allows you to set CSS class on HTML element dynamically by databinding an
* expression that represents all classes to be added.
*
* The directive won't add duplicate classes if a particular class was already set.
*
* When the expression changes, the previously added classes are removed and only then the
* new classes are added.
*
* @element ANY
* @param {expression} ngClass {@link guide/expression Expression} to eval. The result
* of the evaluation can be a string representing space delimited class
* names, an array, or a map of class names to boolean values.
*
* @example
Sample Text
