Changes for version 1.07
- fixes to facilitate subclassing o use ref $this instead of hardcoded "Set::IntSpan" o made internal functions into methods o use method call syntax on all internal method calls, not function call syntax o use direct object syntax on all internal method calls, because indirect object syntax sometimes parses as a function call
- added ABSTRACT and AUTHOR keys in Makefile.PL
