Removed comment and added a 'const' declaration.
Renamed "my" classifier files to "band" classifier.
Added a testing program for a classifier that uses normal distribution
for the positive classifier and a histogram for the negative classifier.
Added a training program for a classifier that uses histograms for both
positive and negative data.
Created new classifiers. Added the prior probability in some evaluation
algorithms.
The CMakeLists.txt of both test and train folders are a mess.
