* MediaProxy is a MediaHandler which

*
* Typically, a MediaProxy reads a text configuration file
* that contains all of the information needed to
* make a connection to a server and obtain media data.
* To produce a Player from a MediaLocator
* referencing the configuration file,
* Manger:
*
* - constructs a
DataSource
* for the protocol described by the MediaLocator
* - constructs a
MediaProxy to read
* the configuration file using the content-type of the
* DataSource
* - obtains a new
DataSource
* from the MediaProxy
* - constructs the
Player using the content-type of the new
* DataSource
