/**
 * @whatItDoes
 * TreeView Component
 *
 * @howToUse
 * This component is used with the inputs and outputs mentioned below.
 *
 * ### Inputs
 * `string` : **path** - The path of this component ;
 * `TreeViewModel` : **data** - The TreeViewModel of this component ;
 * `any` : **load-tag** - The load-tag of this component ;
 * `string` : **node-icon-class** - The node-icon-class of this component ;
 * `boolean` : **loadMoreEnabled** - Is to show and allow load more options ;
 *
 * ### Outputs
 * `TreeViewModelLeaf` : **valueChange** - When selected leaf(value) change ;
 * `TreeViewModel` : **dataLoaded** - When root node data was loaded ;
 * `TreeViewModelLeaf[]` : **leafsLoaded** - When root node data was loaded it returns the list of leafs in the model ;
 *
 * ### Example
 * To use the component, assume this HTML Template as an example:
 *
 * ```HTML
 * <cmf-core-controls-treeView
 *  [path]="_path"
 *  [load-tag]="_loadTag"
 *  [node-icon-class]="_iconClass"
 *  (valueChange)="onValueChange($event)"
 *  (dataLoaded)="onDataLoaded($event)"
 *  (leafsLoaded)="onLeafsLoaded($event)">
 *  </cmf-core-controls-treeView>
 * ```
