=head1 CHILDREN

None

=head1 EFFECTS

None

=head1 DEPENDENCIES

This will only be used within CELL tags.

=head1 USAGE

This is used exactly like HTML::Template's TMPL_VAR. There is one exception -
since you can have variable names inside the parameters, you can do something
like:

  <loop name="LOOPY">
    <var name="$SomeParam"/>
  </loop>

Where the actual name to be substituted is, itself, a parameter.
