     *
     * Base class for form fields that provides default event handling, rendering, and other common functionality
     * needed by all form field types. Utilizes the {@link Ext.form.field.Field} mixin for value handling and validation,
     * and the {@link Ext.form.Labelable} mixin to provide label and error message display.
     *
     * In most cases you will want to use a subclass, such as {@link Ext.form.field.Text} or {@link Ext.form.field.Checkbox},
     * rather than creating instances of this class directly. However if you are implementing a custom form field,
     * using this as the parent class is recommended.
     *
     * # Values and Conversions
     *
     * Because Base implements the Field mixin, it has a main value that can be initialized with the
     * {@link #value} config and manipulated via the {@link #getValue} and {@link #setValue} methods. This main
     * value can be one of many data types appropriate to the current field, for instance a {@link Ext.form.field.Date Date}
     * field would use a JavaScript Date object as its value type. However, because the field is rendered as a HTML
     * input, this value data type can not always be directly used in the rendered field.
     *
     * Therefore Base introduces the concept of a "raw value". This is the value of the rendered HTML input field,
     * and is normally a String. The {@link #getRawValue} and {@link #setRawValue} methods can be used to directly
     * work with the raw value, though it is recommended to use getValue and setValue in most cases.
     *
     * Conversion back and forth between the main value and the raw value is handled by the {@link #valueToRaw} and
     * {@link #rawToValue} methods. If you are implementing a subclass that uses a non-String value data type, you
     * should override these methods to handle the conversion.
     *
     * # Rendering
     *
     * The content of the field body is defined by the {@link #fieldSubTpl} XTemplate, with its argument data
     * created by the {@link #getSubTplData} method. Override this template and/or method to create custom
     * field renderings.
     *
     * # Example usage:
     *
     *     @example
     *     // A simple subclass of Base that creates a HTML5 search field. Redirects to the
     *     // searchUrl when the Enter key is pressed.222
