  @description
  The `md-highlight-text` directive allows you to specify text that should be highlighted within
  an element.  Highlighted text will be wrapped in `<span class="highlight"></span>` which can
  be styled through CSS.  Please note that child elements may not be used with this directive.
  
  @param {string} md-highlight-text A model to be searched for
  @param {string=} md-highlight-flags A list of flags (loosely based on JavaScript RexExp flags).
  #### **Supported flags**:
  - `g`: Find all matches within the provided text
  - `i`: Ignore case when searching for matches
  - `$`: Only match if the text ends with the search term
  - `^`: Only match if the text begins with the search term
  
  @usage
  <hljs lang="html">
  <input placeholder="Enter a search term..." ng-model="searchTerm" type="text" />
  <ul>
  <li ng-repeat="result in results" md-highlight-text="searchTerm" md-highlight-flags="i">
  {{result.text}}
  </li>
  </ul>
  </hljs>
