(Testing version for pip uploading)QT version of FITIT for XANES fitting submodule of a package
It is a testing version for try pip  Installation.
There are Three examples:
environmentPATH\Lib\site-packages\QTFITIT_example_Fephen3
environmentPATH\Lib\site-packages\QTFITIT_example_IHS500
environmentPATH\Lib\site-packages\QTFITIT_example_IHS729

Runnning Program:
(1)Find the example folder:
cd environmentPATH\Lib\site-packages\QTFITIT_example_IHS500
(2)run program
QTFITIT
then QTFITIT GUI will open.
