Changes to mainWFG, added Kolmogorov & vonKarman

Some additions and changes to operate the new functionality in WFG.
- Added Kolmogorov & von Karman aberrations
- Changes to mainWFG to operate the changed to the 'dict' data type syntax. 
- Changes to the main, in order to implement the new functionality of the WFG code, via 'dict' syntax.
So the way it is implemented now is such that you have to comment and uncomment things to trigger each of the aberrations?
