Every file read (written) by the hmm plugin must be in the following
format:
where N, M, pi, A and B are the hmm attributes specified previously.
Example:
2 3 1.0 0.0 0.3 0.7 0.5 0.5 0.2 0.2 0.6 0.3 0.6 0.1
Note: The load and save methods can, as previously described, load/save specific attribute descriptions. In this case, the file which is read/written by these methods should have the same format described above, but include only the specific attribute which is being loaded/saved, i.e, the other attributes should be omitted from the file.
