/*
 * Defines "extensions" to standard Angular directives. Provides attributes that
 * can be included in HTML tags.
 * 
 * SYNTAX: ngx-enabled="true | false"
 * 
 * Enables / disables an element. Currently only supports button elements that
 * include the "button" element. This extension was added since the similar
 * standard Angular "ng-disabled" attribute does not handle buttons that use the
 * ECOMP styling.
 * 
 * SYNTAX: ngx-visible="true | false"
 * 
 * Sets an element to visible / hidden. Different from ng-show / ng-hide as
 * follows:
 * 
 * ng-show=false or ng-hide=true - Element is completely hidden.
 * 
 * ngx-visible=false - Element is not displayed. However, a blank area is
 * displayed where the element would display if ngx-visible is set to true.
