DESCRIPTION : This script file contains functions that are used by authors on the query sections
  of the Molecule Pages (and elsewhere). It only needs to be referenced when author tools (such
  as creation, editing, and deletion links) are available. It makes use of functions from
  molpages.js (functions starting with 'mp').

  All function names start with 'aq' to help avoid naming conflicts.
