table of exposures.

This is part of Qts Model/View pattern.
Fix problems in adding/removing, loading & such.  Can now read from file
or input parmeters by hand.

Change some code that had "If Windows" around it for unknown reason.
Now the same on all platforms.

pyqtgraph does not handle completely flat images so I threw in some code
to catch this.  Set image to None and make the ImageItem border Red when
the image is set to None to keep from crashing.
Change mouse view to display filtered image data.

copy of the filters so that as they are changed, the image is updated
properly.  Now that there is a copy of the filter in the imageView, it
can internally change the images both as we scroll through images and as
we change the filtered values.

Add menu item that allows viewing the local maxima used in the fits.

dimension refers to the direction Up, Down, right, left.
rolldir is reference to horizontal or vertical which also translates to
data axis.
Add in code which allows passing out & viewing the fit points that are
found and used in the fit for calibration.

Fiters for wx are in minixs.gui.wildcards

Create common method for decorating the ROIs
use ImageItem setOpts to 'row-major' and keep the array pure.
Use QRectF instead of QRect so that we can put bounds on the ROIs the
size of the image.

Add filter to file dialogs
Catch errors in calibrate to keep from crashing
change izip to zip for port to Python 3
Catch changes in image filters so that the calibrate button can be
reactivated and we know that the calibration may be invalid

Use full package path to modules
for use of izip encapsulate import from itertools in a try statement and
refer this to the built in zip
encapsulate ConfigParser import in a try to catch the new name of module
(all lower case)

matrix view to use the toggle slot instead of clicked slot.

Allows the user to recall old boundary setting.

Make the Calibration plot color image

Find min and max values of the calibrated data.  The image scale
is now based on this.
Add in mouse position handler which displays image values on the status
bar.

radio box toggle to switch between this and the exposure view.

Add code to save & load calibration file.

to be doing a great job.  THe code was finding boundaries in x and fixng
to [2,193] in y.  Started getting this to do both axes.

Track Last mouse position to be used with the ROI placement
Change so that new ROIs are created near the mouse instead of at
the origin.
Handle deleteing images from the list.
Place energy with image in label above as slider is moved.
Add item to the right  mouse menu to remove All ROIs.

Add in menus for saving/loading the calibration file & import/export
Xtal locations.
Populate Menu item for saving the calibration.
Fix problem with how I was storing the xtal locations in the model. Was
doing corner position
and size.  Needed to be storing location of opposite corners.
Fix some instances how it marks when the calibration is valid.
