Generates sequences by randomly walking a usage profile. 

$USAGE$
<modelname> name of the usage profile from which the sequences are generated
<sequencesName> name of the sequences that are generated
<numSequences> number of sequences to be generated
<minlenght> minimal length of a sequence
<maxlength> maximal length of a sequence
<maxIter> optional; defines the maximal number of random walks performed before aborting and returning with less than <numSequences> generated sequences; default: <numSequences>*10
<validEnd> optional; if true, only sequences that finish in the global END state are allowed; default: true
