RepRapFirmware - Tool

This class implements a tool in the RepRap machine, usually (though not necessarily) an extruder.

Tools may have zero or more drives associated with them and zero or more heaters.  There are a fixed number
of tools in a given RepRap, with fixed heaters and drives.  All this is specified on reboot, and cannot
be altered dynamically.  This restriction may be lifted in the future.  Tool descriptions are stored in
GCode macros that are loaded on reboot.
