G4 function generator

[floesche]

• Overview – state that the functions are vector with values referring to the pattern.
  Also, should state that the first frame is the zero frame. Although in matlab it is valued as 1 (clear this if not true).
  Also, should state that controller uses a modulo of the number of frames. So if a position function is used that has more numbers than the pattern it will not report an error (again I don’t know if this is true in the new version)
• Give examples for what analog output functions can be used for (trigger, sync camera, commands for LEDs, etc. )
