/**
* @module TextFile
* `TextFile` components are file upload components where you can either toggle to upload a file or enter text.
*
* @example
* <TextFile
* @inputOnly={{true}}
* @helpText="help text"
* @file={{object}}
* @onChange={{action "someOnChangeFunction"}}
* @label={{"string"}}
* />
*
* @param [inputOnly] {bool} - When true, only the file input will be rendered
* @param [helpText] {string} - Text underneath label.
* @param file {object} - * Object in the shape of:
* {
* value: 'file contents here',
* fileName: 'nameOfFile.txt',
* enterAsText: boolean ability to enter as text
* }
* @param [onChange=Function.prototype] {Function|action} - A function to call when the value of the input changes.
* @param [label=null] {string} - Text to use as the label for the file input. If null, a default will be rendered.
