Begin refactoring IVTest code
Merge branch 'master' into iv_devel
fix chip label on TrimBitTest histograms when some ROCs disabled.
work on updating IV curve testing
Merge branch 'master' into iv_devel
Large Refactoring of IVCurve code. Interfaces have been simplified and
better abstractions made to RS232 interface. Iseg implementation not
updated.

Switched c++ standard to c++11. Why not already using?

Generation of LATEX docs temporarily disabled.
Wrapped RS232 in an object to re-introduce multiple port functionality.

Renamed VoltageMin and VoltageMax to VoltageStart and VoltageStop for IVCurve
Testing. This is to reflect the new ability to do both forward and reverse sweeps.

Version is now working with a Keithley 2410 Power supply on an Ubuntu laptop.

Iseg implementation still needs to be rewritten but I have no hardware for testing it.
Re-enabled LaTeX document generation.

Renamed HVSupply functions to be more clear.

Updated ISeg implemenation to be compatable with new code. Not tested(ie. doesn't work)
Merge branch 'master' into iv_devel
Added ability for the serial interface to hand device echoing of output data.
Judging from previous code, the iSeg has this feature. Currently no checking
is done to check that the echo'd data is correct.
added some setting reminders to Keithley2410 Code, Inverted voltages on IVCurveTest.
Merge branch 'master' into iv_devel
Minor fixes of IVCurve code. Compliance now settable via GUI.
Merge branch 'iv_devel' of github.com:cfangmeier/pxar into iv_devel

Conflicts:
	tests/PixTestIV.cc
Added Second Reset command for Keithley2410 to work around "undefined header" error.

Fixed timestamp on IVCurve printout.
Fix Memory leak in PixTestIV.
Added connection timeouts on serial ports.
Fixed Missing data and "undefined header" errors.

The missing data error, where the first data point of a sweep would be
dropped was fixed by enabling software flow control(XON-XOFF).

The "undefined header" error was fixed by increasing the inter-write delay
from 1ms to 10ms.
Disabled debug output on RS232
Fixed compiler errors in hvsupply.iseg.cc
