Added abort on compliance for HV Supplies. Not Tested!!
Finished implementing abort on compliance for IV curves. Iseg still needs
to be tweaked, and needs to be tested on deployment platforms. Also added
additional run info to the IV log file.
Fixed typo in Keithley2410 deconstructor.

Switched Keithley from "sweep" mode to "list" mode to better control the
actual sourced voltages.

Removed False positive of compliance trip in Keithley2410.
Fixes to the threshold edge finding algorithm by Jan Hoss:
* Should be able to cope with jittering edged
* Should be able to detect thresholds which start w/ 100% efficiency at DAC 0
First check if we have a threshold for the pixel and then search the result
vector. Should be slightly faster, since found is shorter.
"Threshold is 0" is only true if we look for rising edges. Otherwise we would
always get zero threshold for all falling edge scans.
Cython interface: allow access to setExternalClock and setClockStretch
Add setExternalClock and setClockStretch to Python CLI, bump version.
Merge branch 'master' into threshold_finding
small syntax corrections
made testboard function Sig_SetMode accessible in api to control DTB signals
Rename Python Interface pixel class member from "roc_id" to "roc" to be
consistent with pxarcore api definitions.
new parameter for pretest
improve and parallelize setcaldelvthrcomp
remove serial
changed error (range) to be half of full range
removed FLAG_FORCE_SERIAL from scurves; still not 100% OK
work in progress
Merge branch 'master' of github.com:psi46/pxar
syntax compliance
