add tags to robodoc #101
Description
We should add tags to various methods and functions to show in which scenarios particular algorithms are useful. For instance, the tag transitions would be useful for both Fibonacci transitions and the procession algorithm.
Robodoc accepts the TAGS keyword, and will pull it into the HTML and other documentation format (e.g. https://michael-edwards.org/sc/robodoc/l-for-lookup_lsp.html#robo283), but it won't provide a link to those tags at the top right of the generated, HTML page, for instance, where functions, methods et cetera are linked. A single page with all of the tags listed, along with links to the code documentation for the particular functions and methods would be essential if this is to be at all useful.
