Minor updates and corrections to get fitting working agin.
Analysis/IVCurve: Minor updates and corrections to get fitting working again.
Analysis/tools/Fitting: Correction of error that caused Fitting to fail (extra comment removed outer "block" loop in fitting)
ExportDialog in pyqtgraph: nothing. Was trying to figure out why the buttons were not working. Luke confirms is error, use the right-click on the plot itself to bring up an export dialog.
pyqtgraph/configfile: reintroduced parsing of Point and QPoint so can read data written with those in the text strings. Does not break anything else.
Mosaic Editor: New top dialog box with global scaling, removed "shading" correction from pyqtgraph, several behind-the scenes changes, including allowing the loading of an entire directory (e.g., for tiled image sets), and ability to perform LR/UD flips of images on individual basis to correct for camera / laser orientation issues in some images.
