A port of the figtree library to Android. Some uneeded parts of the original library (matlab wrappers, samples) have been removed too.
You really want to check out the original : http://www.umiacs.umd.edu/~morariu/figtree/
Like the original library, this is LGPL. On android, it builds as a shared library so you can still link it to proprietary programs.
Go in unix/ and run 'make'
