   get_my_roles($uname,$udom,$types,$roles,$roledoms) : All arguments are
   optional.  Returns a hash of a user's roles, with keys set to
   colon-sparated $uname,$udom,and $role, and value set to
   colon-separated start and end times for the role. If no username and
   domain are specified, will default to current user/domain. Types,
   roles, and roledoms are references to arrays, of role statuses
   (active, future or previous), roles (e.g., cc,in, st etc.) and domains
   of the roles which can be used to restrict the list if roles
   reported. If no array ref is provided for types, will default to
   return only active roles.
