=head1 NAME

Sport::Analytics::NHL::Report::GS - Class for the NHL HTML GS report.

=head1 SYNOPSYS

Class for the NHL HTML GS report. Should not be constructed directly, but via Sport::Analytics::NHL::Report (q.v.)
As with any other HTML report, there are two types: old (pre-2007) and new (2007 and on). Parsers of them may have something in common but may turn out to be completely different more often than not.

=head1 METHODS
