This sets the maximum number of individual matches that this rule should find in order for any matches
of this rule to count. If more than this number of matches are found in the text, then none of the
matches in this rule will count. For instance if a rule searches for matches of "a" in "a a r d v a r k", and the maximum is set to 2, then no matches of "a" will be counted at all, because there are more than
2 occurences of "a" in the text. On the other hand, if Max is set to 3 or 4 or any larger value, then
all the matches would count.
The default Max value is -1, which is the equivalent of no maximum limit.
If you want to stop counting after a given number of matches of a rule, without invalidating the matches
that were already found, use StopAfter instead.
