Fifth revision of Alex Brandmeyer's C++ implementation of CARFAC. Moved output structure to deque<vector<FloatArray>, moved coefficient Design methods to CARFAC object, moved tests into carfac_test.cc. Verified binaural output against Matlab using two tests. Added CARFAC_Compare_CPP_Test_Data to plot NAP output of C++ version against Matlab version. Verified build and test success on OS X using SCons with g++ 4.7 (std=c++11).
