    /**
     * @class Ext.form.field.Base
     * @extends Ext.Component

    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 BaseField 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 BaseField 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:__

        // A simple subclass of BaseField that creates a HTML5 search field. Redirects to the
        // searchUrl when the Enter key is pressed.

            // Handle enter key presses, execute the search if the field has a value
            checkEnterKey: function(field, e) {
                var value = this.getValue();
                if (e.getKey() === e.ENTER && !Ext.isEmpty(value)) {
                    location.href = Ext.String.format(this.searchUrl, value);
