=head1 SYNOPSIS

  my $template = Spreadsheet::Template->new(

      processor_options => {
          syntax => 'TTerse'

=head1 DESCRIPTION

This class implements L<Spreadsheet::Template::Processor> to run the template
data through L<Text::Xslate>. In addition to allowing you to use the provided
variables, it also provides some convenience macros to use when writing your
templates:

=over 4

=item format($name, $options)

Declares a named format, which can be used with the C<c> helper. C<$name> is
the name to use for the format, and C<$options> is a hashref to use as the
value for the C<format> entry in the cell.

=item c($contents, $format, $type, %args)

Returns the representation of a cell. C<$contents> is the cell contents,
C<$format> is either the name of a format declared with the C<format> helper,
or a hashref of format options, C<$type> is either C<"string">, C<"number">, or
C<"date_time">, and C<%args> contains any other parameters (such as C<formula>,
for instance) to declare for the cell. C<$type> is optional, and if not passed,
defaults to C<"string">.

=item true

Returns C<JSON::true>.

=item false

Returns C<JSON::false>.
