A simple example of a JQL function that returns all the members of a particular project role. The usage
of the function:

  roleMembers(<roleName>, [<project>]*)

The roleName cannot be blank. The project parameter(s) can be used to limit the search for members to the
passed project(s). If no project is specified, then the function will search through all projects that the
searching user can browse.
