Made the T_Rax_ROI_selector singleton pattern used more robust
Completely changed the T-ROI selector to also be able to work with spectrum data
Reorganized the data structures
Included the xlimits in the main view to also be updated when something is changing in the roi selector and vice versa
Made it possible to upload own etalon spectrum and use a known temperature for ds and us
polynom is still missing
Major Update:
-image in ROI selector now reversed
-maximum intensity in each ROI is shown in graph
-shows a warning msg if it exceed some value
-calibration files are shown in the main graphs
-automatic loading of lamp files...
-minimum size for images was adjusted
-general graphics was tweaked a little bit...

Bugfixes:
-Fixed a conversion issue when you typed in the roi region
Changed Colors again
Added A folder lbl to see where we are right now
Changed Colors for DS and US boxes

Changed Color of ROI rectangles

Removed statusbar from ROI selector

Fixed automatic processing to not open file with "-raw.spe" endings since they should not be processed...
Installed usage of PV names

fixed an error in the string generation of the next or previous filenames
fixed a bug in the conversion of wavelength to data indices
MAJOR UPDATE
Complete Rewrite

Now using PyQt4, although there is still some wxpython left -> using the pub class

the gui was redrawn extensively and has a much more modern look right now

many small changes which cannot be listed here....
changed roi to be
x_min, x_max, y_min, y_max

and not with x and y reversed
just realized that I accidentally deletedall *.ui files of the new design

so i have to redo all of them, this is the start of the main window

now *.ui files are included in the git repository...
recreated the temperature control .ui file
added a statusbar in the main window where x and y coordinates of the mouse are shown
SPE_Module now reads the ROI from SPE 3 vers files and corrects the calibration accordingly
IMplemented ROI Data Manager which does the following:

saves ROIData for given dimensions and recovers them if a img_file with the same dimension is loaded again
Set an "active" state to the resizeable rectangle which is needed because the garbage collector does not delete fast enough old rectangles, which would otherwise become activated in the main window again...
x_limits are now also shown in main "temperature window"
starting size of windows is now adjusted,
roi selector will be aligned to the base of the main windows when roi-setup buttons are clicked
x-limits are now hidden when we have are using an image file... for temperature stuff
Added the calibration procedures, now everything for temperature calculation is working...
