Improve FindPeaks.  Refs #7001.
Corrected a major error.  Refs #7001.

The algorithm to handle FitWindows were based on a wrong definition.
The code is corrected such that FitWindows specify the range data to fit
a peak.
Fixed a bug.  Refs #7001.
Improved consistency between 2 algorithms.  Refs #7001.
Ignore super wide peaks.  Refs #7001.
Added specific support for flat background.  Refs #7001.
Add property minimum peak height.  Refs #7001.
Tried to resolve a potential conflict in header.  Refs #7001.
