[Task] Solve the issue with GSAS tab reset

1. Locate where the error occurs.

   File "/SNS/users/y8z/miniconda/envs/addie_env_3/lib/python3.6/site-packages/addie/main.py", line 772

2. Identify what causes the issue from the error message.

   AttributeError: module 'addie.calculate_gr.event_handler' has no attribute 'do_reset_gsas_tab'

   • Go to ADDIE source code folder of local conda environment and it seems we are going to worry about the file calculate_gr/event_handler.py.

   • Open that file with preferred text editor and see whether we can find the definition of do_reset_gsas_tab.

   • If it is not defined, definitely we will have issue during program running.

3. Solve the issue.

   • Search for do_reset_gsas_tab in the whole ADDIE source codes.

   • Point Reset GSAS-tab menu to where do_reset_gsas_tab is defined.

     do_reset_gsas_tab \rightarrow BraggTree \rightarrow main_window.rietveld_ui.treeWidget_braggWSList.

A live working session may be needed to work through this issue.
