Fixed conversion of parameters to array.
Added testWFS.py to test the mainWFS.py. Also made lensCentx/y into arrays in the parameter sensor, it should have been like this form the beginning.
Improved test function, also now testing zero phase input.
Removed part of the redundant variables in paramsSensor and the sampling of the image plane is now adjustable in mainWFS.

Now with the current master.
Merge pull request #68 from faitdivers/issue66

Merging it. Tested here and it works, and there is already a new issue created for the code readability. I don't totally agree with this approach, but the main issue to be solved was #66 and that is fixed now.
