hfst.regex() documentation: ^>n catenate less than n times

[koskenni]

Help text of function regex in module hfst should be corrected. It reads now ():

regex(re, **kwargs)
...
^n,k catenate from n to k times, inclusive
^>n catenate more than n times
^>n catenate less than n times
^n catenate n times

I assume that ^<n does the less than n times concatenation.
