Added a function {\makehashsign} to allow users to insert a hash sign into the LaTeX markup of their template strings. This is needed because a hash symbol inside a template string indicates a comment.
Updated the Bibulous documentation.
Modified test2 in the testing suite to use the \citation{*} notation rather than calling out each individual citation in a very long list.
Added 'validate_templatestr()' to bibulous.py, providing a single location where we can put all of our checks to verify that a template string is formatted correctly.
