=head1 NAME
TM::Index::Characteristics - Topic Maps, Indexing support (match layer)
=head1 SYNOPSIS
# somehow get a map (any subclass of TM will do)
my $tm = ...
# one option: create a lazy index which learns as you go
use TM::Index::Characteristics;
my $idx = new TM::Index::Characteristics ($tm);
# for most operations which involve match_forall to be called
# for querying characteristics should be much faster
=head1 DESCRIPTION
This index can be attached to a map if querying it for characteristics (here names and occurrences)
is intensive.
The package inherits most of its functionality from L<TM::Index>.
=head1 INTERFACE
=head2 Constructor
The constructor/destructor is inherited from L<TM::Index>.
