a note about naming scheme -
for example, functions_aggregating_avg is a label for the avg function
i tried to make it the cypher manual section (functions), then the asciidoc file (or functions group, "aggregating") and then the function in that page

we probably do not have to be super religious with schemes, but i thought i'd bring it up :)
