Improved postprocess performance by pruning the characterset before sending to the recursive sort.
This uses the "topN" value to remove lower scoring characters that couldn't possibly show up in the topN results
Merge https://github.com/vebers/openalpr into develop
Updated postprocess permutation calculation to handle corner cases (topn = 1 and permutations == topn)
Print all the letters (debug output) in postprocess before pruning them
Tweaked binarize functions to do integer multiplication rather than float -- slightly faster
Using cmake to set the default runtime_dir (relative to the source path).
Removed errant tinythread.cpp reference
Updated cmake relative paths (simplified & removed boilerplate)
Added .gitignore entries
Declared minimum opencv version at 2.4.8 (required for opencl)
Cleaned up include statements
Removed unused includes in main
Incremented version
