New in QXRD 0.5.18 (Jun 7, 2011)

New in QXRD 0.5.17 (Jun 7, 2011)
- contains fixes and changes to the 'synchronized acquisition' mode
- Added a 'bipolar triangle' waveform.
- Added nidaq.getAnalogInput and nidaq.setAnalogOutput script commands. Added display of syncronization waveform to UI
New in QXRD 0.5.16 (Jun 7, 2011)
- mainly involves a major re-write of the acquisition code to support 'synchronized' acquisition. This involves taking 'groups' of images while varying an external programming voltage (using a supported National Instruments NI-DAQ card). You specify the number of images in a group and then QXRD adds together multiple cycles of acquired images in phase with the output waveform. The acquisition code does not currently support the pre-trigger acquisition mode of earlier versions. I was hoping to remove this, but it seems that people are actually using it so I had better put it back in. The functions and parameters are there, but they don't do anything at the moment.
