The MKVFile class can either import a pre-existing MKV file or create a new one. After an MKVFile object has

respectively.
Tracks are always added in the same order that they exist in a file or are added in. They can be reordered
using move_track_front(), move_track_end(), move_track_forward(), move_track_backward(), or swap_tracks().
After an MKVFile has been created, an mkvmerge command can be generated using command() or the file can be
muxed using mux().

Path to a pre-existing MKV file. The file will be imported into the new MKVFile object.
