Example for Roessler-Oscillator; minor fixes on model code
Example for Roessler-Oscillator; now file included
Merge branch 'master' of https://github.com/peircej/eegpy into develop

New file format implementation.
Completed integration of DBPA format

Complete refactoring: DBPA and F32 now inherit from the same
baseclass, MemoryMappedBinaryDataFile. Code redundancy is minimal.

Also, a new base class for filtered reading is created, and both
F32filtered and DBPAfiltered inherit from it.
