TheDocs Release

Warning: this release is not backwards compatible! It removes several inconsistencies and improves the functionality of definitions defined prior to this release, which could cause issues if the new templates are compiled with old documents.

Major overhaul of template documentation, combining comprehensive documentation (and a basic LaTeX tutorial) into the new document 'TheDocs.pdf'.

Significant extra functionality has been added to tables to make them much easier to use, and considerably simpler and more powerful.
