/**
 * @whatItDoes
 *
 * The EnumComboBox displays a ComboBox for a given Enum.
 *
 * It will show in the ComboBox all the entries that are not numbers, as is.
 *
 * It should be used then we need to select a value from an Enum.
 *
 * This component uses the ComboBox component.
 *
 * @howToUse
 *
 * This component is used with the inputs and outputs mentioned below.
 *
 * ### Inputs
 * `enum` : **enum** - The enum that needs to be displayed by the ComboBox
 * `number` : **value** - *(from ComboBox Component)* The current value in the ComboBox
 * `boolean` : **required** - *(from ComboBox Component)* Indicate if this is required
 * `string` : **placeholder** - *(from ComboBox Component)* ComboBox placeholder
 * `boolean` : **disabled** - *(from ComboBox Component)* Indicate if this is disabled
 * `boolean` : **singleElementPreSelect** - *(from ComboBox Component)* Should select a single element
 *
 * ### Outputs
 * `number` : **onValueChange** - When the value of the Enum changes, this output emits the new value
 *
 * ### Example
 * To use the component, assume this Typescript and HTML Template as an example:
 *
 * ```Typescript
 * enum MyEnum {
 *  Entry1 = 0,
 *  Entry2 = 1
 * }
 * ```
 *
 * ```HTML
 * <cmf-core-controls-enumComboBox
 *  [enum]="MyEnum"
 *  (valueChange)="onEnumValueChange($event)"
 * ></cmf-core-controls-enumComboBox>
 * ```
 *
 * This will produce a ComboBox that will show "Entry1" and "Entry2"
