=head1 NAME
FS::o2m_Common - Mixin class for tables with a related table
=head1 SYNOPSIS
use FS::o2m_Common;
@ISA = qw( FS::o2m_Common FS::Record );
=head1 DESCRIPTION
FS::o2m_Common is intended as a mixin class for classes which have a
related table.
=head1 METHODS
=over 4
=item process_o2m OPTION => VALUE, ...
Available options:
table (required) - Table into which the records are inserted.
num_col (optional) - Column in table which links to the primary key of the base table. If not specified, it is assumed this has the same name.
params (required) - Hashref of keys and values, often passed as C<scalar($cgi->Vars)> from a form.
fields (required) - Arrayref of field names for each record in table. Pulled from params as "pkeyNN_field" where pkey is table's primary key and NN is the entry's numeric identifier.
