This mediator will use the specified command object and execute the command after setting
the properties specified to it through the configuraiton. The specified command object may or
may not implement the Command interface. If the Command object has not implemented the Command
interface then this will use reflection to find a method called execute() and execute it.
Implements the mediate method of the Mediator interface. This method will instantiate
a new instance of the POJO class, set all specified properties from the current runtime
state (and message context) and call the execute method of the Command object.
