Suggestion: create human-friendly schema browser

[joerivandervelde]

Some users would like to use the schema as a reference to e.g. fill in data submission forms. However the current Markdown format is just a big list of tables and the lookups are TXT files that cannot be searched conveniently. We received a suggestion to generate fancy looking (truly interactive) HTML pages where modules, elements and lookups can be browsed, including search options for big lookup lists, perhaps a bit similar to presentation of OLS.
