Algorithm::info()-related code disabled-after moving to opencv_contrib caused compilation errors Added usage examples Added documentation for optflow_io +bugfix: handling invalid algorithm choice + solving MSVC compilation errors; assuming that int and float are 4-bytes long - possibly needs fixing
