/**
 * @whatItDoes
 *
 * This component is used in order to display a dropdown list of entries.
 *
 * This component differs from the standard dropdown list in the following
 * ways:
 *
 * * It displays a label on the dropdown title containing the number of
 *   entries that are currently selected on the dropdown list.
 * * If there are no entries selected in the dropdown, then it assumes that
 *   all of the entries are selected.
 *
 * @howToUse
 * This component is used with the inputs and outputs mentioned below.
 *
 * ### Inputs
 * `string[]` : **entries** - The entries to display in the dropdown list.
 * `string[]` : **selectedEntries** - An array containing the strings that
 * represent the entries that are currently selected in the dropdown.
 *
 * ### Outputs
 * `Cmf.Foundation.BusinessObjects.Entity` : **selectedEntriesChange** - Emits
 * an array containing the entries currently selected in the dropdown list.
 *
 * ### Example
 * To use the component, assume the following HTML Templates as examples:
 *
 * ```HTML
 *   <cmf-core-business-controls-dropdownEntitySelect
 *     [entries]="entries"
 *     [selectedEntries]="selectedEntries"
 *     (selectedEntriesChange)="onSelectedEntriesChange($event)">
 *   </cmf-core-business-controls-dropdownEntitySelect>
 * ```
 *
 * ### Dependencies
 *
 * #### Components
 * Dropdown : `cmf.core.controls`
 *
 * #### Services
 * _This component does not depend on any service._
 *
 * #### Directives
 * _This component does not depend on any directive._
