Detailed Description

Moves data from one place to another, converting it as required.

Shuttle provides a base class for transferring parameter data into and out of classes into some other structure. This is a common requirement and is needed for:

• Prefs data
• Command line parameter data
• Project data in XML

The 'Master' is the string side of the shuttle transfer, the 'Client' is the binary data side of the transfer.
