=head1 ANALYSIS

=head2 $strap->analyze( $name, \@output_lines )

    my $results = $strap->analyze($name, \@test_output);

Analyzes the output of a single test, assigning it the given C<$name>
for use in the total report.  Returns the C<$results> of the test.
See L<Results>.

C<@test_output> should be the raw output from the test, including
newlines.
