Redline source folders will be created based on pre-existing java folder
structure.  

2. When the smalltalk source folder is added it should follow this
logic:
    2.1 If there is a src/main then the source folder to add is
src/main/smalltalk
    2.2 If there is a src/test then the source folder to add is
src/test/smalltalk
    The above two options cater for people following the maven project
layout.
    2.3 If there is only a src folder then the source folder to add is
/smalltalk 
         like you have done but names smalltalk rather than redline.
