Triceps 2.0.1 released

This time I'm trying to update the docs following the code changes, and do the small releases.

The release 2.0.1 is here! It includes:

• Fixed the version information that was left incorrect (at 0.99).
• Used a more generic pattern in tests for Perl error messages that have changed in the more recent versions of Perl (per CPAN report #99268).
• Added the more convenient way to wrap the error reports in Perl, Triceps::nestfess() and Triceps::wrapfess().
• Added functions for the nicer printing of auto-generated code, Triceps::alignsrc() and Triceps::numalign().
• In the doc chapter on the templates, fixed the output of the examples: properly interleaved the inputs and outputs.
