Quick Dirty Command Line Parser Isn't working

Hi,

I made a quick command line but not sure why it's not working? It seems the for loop is wrong.

The code results in this.

$ ./AlphaToolbox --makegameassets --template test.xml --sourcepath /BuildPath/bin/GameData/Models/ --destpath /BuildPath/bin/testoutput/
AlphaToolBox Utility 1.0 
Parameter - SourcePath :--makegameassets--templatetest.xml--sourcepath--destpath/BuildPath/bin/testoutput/
Parameter - DestPath :--makegameassets--templatetest.xml--sourcepath/BuildPath/bin/GameData/Models/--destpath
Parameter - TemplateFile :--makegameassets--template--sourcepath/BuildPath/bin/GameData/Models/--destpath/BuildPath/bin/testoutput/
Error: No mdl file in source path

The first argument (0) is always the executable (and path). So start the loop with i=1.

.append(...) isn't a good idea especially for useargument. When you pass useargument like on line 53/59/65 all previous arguments are passed as well.

You might pass a string like

"test.xml/BuildPath/bin/GameData/Models//BuildPath/bin/testoutput/"

on line 59.
