_do_move_abs not connected?

[mvbnano]

On branch _pi_usb_digital_control (and likely pi_pci_digital_control) the function _do_move_abs does not appear to be called. It appears to have been written (by QMAPP devs) do be a better way of setting the scanner position, whereby you can not move out-of-bounds.

Prior to merging upstream this should be looked in to.

This now applies on branch dev_ntmdt_stage also.

This now applies on branch dev_newfocus_screws also.

[mvbnano]

This is now smartly implemented in ntmdt_piezo_stage.py on branch dev_ntmdt_stage. This should be used as a standard for the implementation on our other development branches.

Can be resolved on branch dev_newfocus_screws once issue #28 has been resolved.

[mvbnano]

Implemented smarter absolute movement on all dev branches excluding dev_newfocus_screws.

@MyrddynEmrys Once your constraints are loaded as per issue #28 we will implement constraint checking on that branch too.
