Adding in changes to developement branch
Deleting old directory for xcode
Merge branch 'developement' of https://github.com/jacobwjs/AO-KWave-MCBoost into developement
Found the bug.  Had to do with taking the modulus of zero.
Adding latest changes.  A lot of work done for notifications about MC-Boost medium
and attributes, as well as added options for selectively choosing which
AO mechanisms to simulate.  There was also an issue with the detector plane
not being set, which is now fixed.

However, there is an issue with detecting photons after initial seed generation.
That is, using seeds during the next run produces 0 detected photons.  Comitting
this for debugging on OSX.
