Missing returned values

Issue in ./help/profile/computed-attributes/overview.md

In the table that describes the functions, it would be useful to have the type of data returned by the function. For example, I'm trying to use the output of "MOST_RECENT" function in AJO and it seems that it returns an array of strings, not a string.

Open help/profile/computed-attributes/overview.md and review the table describing the functions. Determine and add the returned data type for each function, including whether MOST_RECENT returns an array of strings; the work is done when the table documents these return types.
