/**
 * The TextField is a wrapper component for the built in `<input>` tag.  This
 * control allows the user to add validation routines to the input control
 * beyond the builtin routines.
 *
 * Validations are used by creating an instance of the `Validator` class and
 * implementing a validation funtion, failure message, and success message.
 *
 * Validation is NOT used by default.  It must be declared with a prop named
 * `usevalidation.  The control has five built in validation routines (defined
 * in validator.ts):
 *
 * - max length (when used with the "max" parameter)
 * - min length (when used with the "min" parameter)
 * - email
 * - url
 * - regex
 *
 * ## Screen:
 * <img src="https://github.com/jmquigley/gadgets/blob/master/images/textField.png" width="60%" />
 *
 * ## Examples:
 *
 * ##### Simple
 * ```javascript
 * import {TextField} from 'gadgets';
 *
 * <TextField placeholder="simple" />
 * ```
 * This will create a standard input text box with no validation.
 *
 * ##### Max/Min validator
 * ```javascript
 * import {TextField, TextFieldType} from 'gadgets';
 *
 * <TextField
 *     initialValue="abcde"
 *     maxLength="10"
 *     minLength="5"
 *     placeholder="min/max validation"
 *     type={TextFieldType.text}
 *     usevalidation
 * />
 * ```
 *
 * This will create an input control that uses validation.  It will check the
 * width of the string to fall within the min/max range.  When the string is
 * outside of the validation range the red *error* message value will be used
 * too display a message below the control.  When it is within range a green
 * *success* message will be printed below.
 *
 * ##### Custom validator
 * ```javascript
 * import {TextField, TextFieldType, Validator} from 'gadgets';
 *
 * <TextField
 *     placeholder="custom"
 *     type={TextFieldType.text}
 *     usevalidation
 *     validators={[
 *         new Validator(
 *             (value: string) => {
 *                 return /^[0-9a-zA-Z]+$/.test(value);
 *             },
 *             'Not alphanumeric only',
 *             'Contains only alphanumeric'
 *         )
 *     ]}
 * />
 * ```
 * This will create a control with a custom alphanumeric validation routine.
 *
 * ## API
 * #### Events
 * - `onBlur` - Invoked when focus on control is lost.
 * - `onChange` - Invoked each time a key is pressed.  The validation routine is
 * also called with each key.
 * - `onClear` - Invoked when the clear button is pressed in a search text control
 * - `onKeyDown` - Invoked when a key is pressed.  The escape key is checked
 * and if pressed the input is reverted to its previous setting.
 * - `onKeyPress` - Invoked when a key pressed.  When the "Enter" key is pressed
 * validation is performed and the `onValidation` routine is invoked and the
 * results of the validation are sent to the callback.
 * - `onValidation(flag: boolean)` - When enter is pressed this routine is
 * called.  If validation passes, then true is given to the callback.
 *
 * #### Styles
 * - `ui-textfield` - Placed on the `<div>` used to wrap the `<input>` field.
 * - `ui-textfield-validation-message` - Placed on the `<div>` used to wrap the
 * validation message when the input contains validation code.
 *
 * #### Properties
 * - `disabled=false {boolean}` - When true, the control is disabled
 * - `id='' {string}` - The CSS id for this control
 * - `initialValue='' {string}` - The first value set within the control.
 * This is only done one time when the compoment is constructued.
 * - `max='any' {string}` - the maxium number for a spinner text box.  When
 * set to "any" there is no size.
 * - `min='any' {string}` - the minimum  number for a spinner text box.  When
 * set to "any" there is no size.
 * - `noborder=false {boolean}` - Turns off the border around the component
 * - `sizing=Sizing.normal {Sizing}` - The font size for the control (see
 * the Sizing class in shared).
 * - `step='any' {string} - the increment number for a spinner text box.
 * When this is set to "any" the step is 1 by default.
 * - `type=TextFieldType.text {TextFieldtype}` - The type of input control.
 * This is the type defined by the [HTML input tag](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input).  The
 * value is an enum that maps to these valid types.
 * - `useclear=false {boolean}` - When used it presents a circle "x" button
 * that will clear the current input from the control and set the focus to
 * the input.
 * - `usevalidation=false {boolean}` - If this is true then the validation
 * routines are exectued.
 * - `validators=[] {Validator[]}` - A list of Validator classes.  Each of the
 * classes in this list are used against the input to check if it passes the
 * rules set in that validator function.
 * - `value=undefined {any}` - This is will override whatever is currently in
 * the control.  It should only be used if the parent is going to control the
 * contents of the control.
 * - `visible=true {boolean}` - If set to false this control is hidden (set
 * to a display of none).
