Module::CPANTS::Kwalitee::MetaYML - Checks data available in META.yml
=head1 SYNOPSIS
Checks various pieces of information in META.yml
=head1 DESCRIPTION
=head2 Methods
=head3 order
Defines the order in which Kwalitee tests should be run.
Returns C<10>. MetaYML should be checked earlier than Files to
handle no_index correctly.
=head3 analyse
C<MCK::MetaYML> checks C<META.yml>.
=head3 kwalitee_indicators
Returns the Kwalitee Indicators datastructure.
