Takes a high-order Markov model as input and creates an equivalent first-order Markov model through state splitting.

Note: command probably broken because of the refactoring of the event core!

$USAGE$
<modelname> name of the high-order Markov model
<modelname_flattened> name of the equivalent first-order Markov model that is created

Example(s):
flattenModel 5thOrderMarkovModel 5thOrderMarkovModel_flattend
