 Dictionary was replace by class   
 
1- [Problem] Data loaded from files of 2 columns do not have group_id as field.
   thus will always generates a theory unattached to data (2 columns) 
   
2- [Problem] not fit able to fit 2 data and one model  since unable to select
	 two data at the same time.       
	 
3- [Problem ] when fitting two model of same nature   how will the user entered the proper expression
    Need a txtcrl to specify a new name for a each type model
    example lineModel = M1
    		lineModel = M2   
 [solve] but can be improve?
    
    		
 4- I create a page given an group_id  so the 2 columns data need group_id to be add twice 
 since for them i create a page call fit but if a page called fit is already added it will not
 added again if a 2 nd data of 2 columns is selected    
[Question] if  a page is not created should i post a status event message?  


5- [To Do]take care of data range with park

6- [Problem]when the user close the fitting panel and load a data and what to do the fit again with the 
the panel fit does not show up automatically
[solve]

7- [To do ]we need a way to close tab may be a close button for current tab
	[solve] close button added

8- [Problem ] when selecting all check buttons manually , the main check button does
 not changed accordingly
 [FIXED]
 
9- [Problem] when the user select a model first and want to perform a fit , we should fine a 
 way to give the data the same group_id as the model loaded.
 [ANSWER] the user will perferm the fit only starting by loading data
 [tentative of answer]  when selecting a model from the menu is the draw in the separate 
 window from data. it is only when selecting data that a fit page is added
 
 10- [Problem] How to tackle the problem the other way around? when the user select a model 
 from the menu bar , does a new place has to be create to? which name to give to this page?
 since when loading a data a new page is created?
 []SAME ANSWER AS 9]

 11-[TO DO] when enter value in parameter fields redraw model 
 [DONE]
 
 12-[TO DO] comment code and refine
 
 13- [UNABLE TO USE] post event on status bar and use calthread
 [solve] except calthread
 
 14- [TO DO] more error checking
 
 15-[suggestion ] keep only one button close and close the current page except simpage 
 [suggestion accepted]only one close button to close the current page
 
 
 16-[Question]redraw with evt_kill_focus or evt_text_enter
 
 17-[QUESTION] does the model need to be redraw when change fitting data range?
[tentative of answer] _ontextEnter : when xmin and xmax changed redraw model
[fixed]


18-[Problem] when fitting cylinder model with cylinder data some fitting results are swapped
[fixed] sort() method not remove yet

19-[problem] when closing a windows model fitted doesn't disappear fron simpage
[fixed]

19-[Problem] how to catch not converging fitting? both scipy and park?
 exception: raise LinAlgError, 'SVD did not converge'
LinAlgError: SVD did not converge

20- fitness class in Models was helping to overwrite a theory plot since always 
has the same name: so do I put back fitness class or always name theory with fitness?

21- [question] should the data being replot when changing xmin and xmax???

22-[Question ] how to best design sim_page functionalities?
23- [Question] how to use one object result from scipy? park returning one result
