added \t's to print statements for neater format
modified print statement
renamed computeLocationForPolarCoords to computeCartesianFromPolarCoords
added empty plotRuntimes script
replaced myWorld->getNumObj with numObj in performMix
added intermed output bufs, removed extra code for addAudioObjToMix

By first computing output and storing it in the intermediate output
buffers the time each thread needs with the lock on the actual output
buffers is lessened, since no computation is being done. Values are
now just being copied from intermediate to output buffers.

We were also computing the final output twice, so the second computation
was removed. This had no noticeable effect earlier becuase it was
in effect just making the output twice as loud.
modified print statement to be compatible with python script

plotRuntimes.py parses output assuming the following format:
Runtime for <function name>: <runtime>
removed iOSSonic print statements
added buf_size, etc. print statements
implemented plotRuntimes.py, need to test
commented out print statements, uncommented throw for WavObj
made print statements easier to parse

before: Runtime for <functionName>:\t\t<runtime>
after: <functionName>\t\t<runtime>
added *.pyc, .*.swp to .gitignore
added new, cleaner test data
added *.pyc, *.swp to .gitignore
removed whitespace from print statements for easier parsing
graph plotting script working
reorganized graph and data dirs
removed whitespace
