/**
 * @whatItDoes
 *
 * Implements the File step of the Export wizard.
 *
 * This step allows the user to select a file that will contain the
 * exported data.
 *
 * @howToUse
 *
 * ### Inputs
 * None.
 *
 * ### Outputs
 * `string | null` : **fileNameChange** - Indicates when the file name
 * to be used on the export has changed. It is a string containing the
 * file name to use, or "null" if no file name is provided.
 *
 * `boolean` : **compressFileChange** - Indicates if the file created
 * by the export backend service should be compressed. It is a boolean
 * where the "true" value means that the exported file will be
 * compressed into a zip file or "false" which means that the export
 * file will be a normal xml file.
 *
 * ### Example
 * To use the component assume this HTML Template as an example:
 * ```HTML
 *     <cmf-core-business-controls-wizardExport-file-step cmf-core-controls-validator
 *         (fileNameChange)="onFileNameChange($event)"
 *         (compressFileChange)="onCompressFileChange($event)">
 *     </cmf-core-business-controls-wizardExport-file-step>
 * ```
 *
 * ## StepFile component
 *
 * ### Dependencies
 *
 * #### Components
 * * BaseWidget : `cmf.core.controls`
 * * PropertyEditor : `cmf.core.business.controls`
 * * PropertyContainer : `cmf.core.business.controls`
 *
 * #### Services
