Added new test for de_branch issue, changed az_branch test name to allow for both tests.
Update 11.5.2013 0942

Modified files in an attempt to correct the DE branch point issue.
DE branch points now only produce one eigenray but they are drastically erroneous and therefore need to be corrected.
Moving to another branch until the new issue #43 is resolved as #36 is a dependent.
Update 11.5.2013 1133

Added new study, WaveQ3D Visualization. This study will allow us to change the visualization scenario easily and hence present an easy way of showcasing the properties of waveq3d.
moved to waveq3d visualization studies directory.
Update 11.6.2013 1225

speed_test.cc:		Commented out redundent define of USML_DBEUG
wave_queue.cc:		Added AZ boundary conditions back in and updated to avoid indexing issue with with skip_az matrix
Updated azimuthal boundary loop, no longer attempts to access an invalid index
Somehow the variables did not make it into the last push update.
Update 11.7.2013 1057

With the introduction of looping around the azimuthal boundaries within the spreading_hybrid_gaussian and thus accumulating all possible ray contributions on the first instance of creating an eigenray, it no longer became necessary to search for more eigenrays for the specific target at that instant in time and azimuthal angle, and therefore could break out of the search loop and go to the next target.

This assumption is based that only one eigenray can be created for any given combination of azimuthal angle, time, and target. It present it does as required.
Removed bool to break loop once and eigenray is found as thi was a faulty assumption. It appears that with the looping around the az boundary resolves the production of multiple rays at the branch point appropriately with out this faulty boolean.
Pulled in correct az branch point logic into this branch to continue with de branch point issue.
Commented out define for USML_DEBUG. 
Cleaned up comments.
Merge of AZ Boundary Point Feature Fix
Update demo_gui.m

Added few more options
Added more DEBUG OUTPUT for Eigenray.
demo_gui version 2.0 as been added with all necessary m files.
Still investigating the issues with the de branch points and the antisymmetry seen in the computations that are not expected.
Added newest version of the demo gui to deve0.04 repo.
Added latest version of demo_gui.
Added canned scenario nc files to repo for quick easy access.
Corrected the detection logic in the is_closest_ray call to now appropriately skip only in the de directions as opposed to both de and az. This now prohibits the procurement of obscure eigenrays that were never close to the target.
