damaris-backends/machines/damaris.cpp
Markus Rosenstihl ce944d3e41 new backend, hopefully more flexible
changing gtklib to boost config file reader as that seems to be
easier and more c++ like. Also does boost provide more possibilities
in the future than glib2-

Uses Spincore Pulseblaster 24 Bit and Spectrum MI4021, PTS310 with cabledriver with phase control and a synchronization board
or dummy or tempcontrol or ...
\li line 0 for gate
\li line 1 for pulse
\li line 17 for trigger
\li line 16 for synchronization
\par Starting the hardware
This procedure should assure the correct initialisation of the hardware:
\li Switch off main switches of SpinCore Pulseblaster and Computer (the main switch of the computer is at the rear)
\li Switch on Computer and start Linux
