EPGM Menu moves to 'Menu' sheet      
Edit Inputs moves to 'Inputs' sheet      
Run loads currently selected case & runs model    
Output Summary moves to 'Results' sheet      
Upstream increases output distance by 0.1 km (affects results on graphs_site sheet)
Downstream decreases output distance by 0.1 km (affects results graphs_site sheet)
Restart restarts simulation (sets output time to 0 years)    
Next Year moves output time forward by 1 year    
Previous Year moves output time back by 1 year    
Animate cycles through each year in sequence; press 'Esc' to stop  
If the Toolbar remains after closing EPGM, right click on it and uncheck the EPGM box.
