function CBScript = MAIN_TOOL_script_generator(task)
%{
 Uicontrol callback script generator for the main GUI.
--------------------------------------------------------------------------
Syntax :
CBScript = MAIN_TOOL_script_generator(task)
--------------------------------------------------------------------------

Function Description :
This function generates scripts for the main GUI uicontrols. MATLAB's
uicontrols (pushbuttons, edit boxes, etc...) allow for a script to be
executed when the user interacts with them. The script is called
callback. The scripts are generated as text arrays. The task input 
variable inidicates which script to return. No other inputs are
necessary. 
The list of possible tasks is the following :

         1) Save & Close
         2) Save Visualisation
         3) Save All Data Structures
         4) Update Visualisation
         5) Open Subject Specific Tool
         6) Open Initial Configuration Tool
         7) Open Muscle Tool
         8) Open Joint Sinus Cone Tool
         9) Open Ribcage Ellipsoid Tool
         10) Open Kinematics Tool
        11) Open Check Muscle Moment Arms Tool
        12) Open Muscle Force Estimation Tool
        13) Help
