* Class that represent the Callback action.
*
* The result option array entry value is set to the return value of the
* callback defined in the option.
*
* There are two steps to defining a callback option:
* - define the option itself using the callback action
* - write the callback; this is a function (or method) that takes five
* arguments, as described below.
*
* All callbacks are called as follows:
* <code>
* callable_func(
* $value, // the value of the option
* $option_instance, // the option instance
* $result_instance, // the result instance
* $parser_instance, // the parser instance
* $params // an array of params as specified in the option
* );
* </code>
* and *must* return the option value.
