/**
|
||||
* This module implements a drivable for running the eiger A2 motor.
|
||||
* The problem with that one is that the slits have to follow it.
|
||||
* In addition the slit width needs to be adjusted too. All this
|
||||
* is done in this module.
|
||||
*
|
||||
* CAVEAT: This module requires for its working the existence
|
||||
* of 3 motors in SICS:
|
||||
* a2rot, d2r, d2l
|
||||
* As this module is very special to EIGER no special checks have
|
||||
* been implemented on this. SICS will assert and fail if this
|
||||
* condition is not met.
