added chisq.cpp and chisq.h
fixed chisq.h
added preprocessor statements to .h files
added udder and wmaplikelihood to chisq.cpp
made other code compatible with chisq.cpp
changed aps_interface.cpp to support ellipses and s_curve
updated to modern gaussian_process.cpp as of December 4 2013
added hyperparameter ranges to gaussian_process.cpp
added self_predict to gaussian_process
added rudimentary optimization to gaussia process
time to test optimization
gaussian process no longer uses global max and min
optimization seems to work
now usual sampling occasionally focuses on region where we know there are good points
focusing works in the sense that it does not crash
focusing seems to yield results now
removed all reference to failed node sampling option
folded aps sampling and gradient sampling into one search routine
gp optimization now shows every hyper parameter in every step
added add_candidate routine
