New diffractometer setup

[gfabbris]

New devices:

• Simulated diffractometer (diffract device) of our new instrument. Using the Petra geometry, see hkl manual for details on motors and modes.
• Simulated detector (simdet device, generates random [0, 1) numbers) with a count time.

To test this, first make sure that you are in the correct branch (new-diffractometer), start bluesky using blueskyStarter.sh, then:

In [6]: simdet.count_time = 0.1

In [7]: RE(bp.rel_scan([simdet], diffract.mu, -2, 2, 10))
