Refactor curvefit.fitWLC_regions
Little refactor to fplot.PlotStyle
Add fileIO.loadofc for binary force clamp data
datatypes: tabbing => 4 spaces
Major revisions to experiment module and classes

1) Remove RipAnalysis => considering turning it into another module.
Will be able to find rips, assign states for fec, etc., calling it
"fecmath" or something

2) Made experiment.Base.figure private and read-only

3) Fixed bug in save() which prevented experiment object pickling
when figure objects are present.

4) Upped forceOffsetRange to (760, 790)
Add path kwarg to experiment save functions; os.path => opath
Temp fix of experiment.Base.save() when has been fit
Keep track of regions in Fit object
