/**
* @docauthor Robert Dougan <rob@sencha.com>
*
* Single radio field. Similar to checkbox, but automatically handles making sure only one radio is checked
* at a time within a group of radios with the same name.
*
* # Labeling
*
* In addition to the {@link Ext.form.Labelable standard field labeling options}, radio buttons
* may be given an optional {@link #boxLabel} which will be displayed immediately to the right of the input. Also
* see {@link Ext.form.RadioGroup} for a convenient method of grouping related radio buttons.
*
* # Values
*
* The main value of a Radio field is a boolean, indicating whether or not the radio is checked.
*
* The following values will check the radio:
*
* - `true`
* - `'true'`
* - `'1'`
* - `'on'`
*
* Any other value will uncheck it.
*
* In addition to the main boolean value, you may also specify a separate {@link #inputValue}. This will be sent
* as the parameter value when the form is {@link Ext.form.Basic#submit submitted}. You will want to set this
* value if you have multiple radio buttons with the same {@link #name}, as is almost always the case.
*
* # Example usage
*
* @example

* title : 'Order Form',
