/** \brief Routines to parse grouping policies.
*
*
* Grouping-policy configurations are written as follows:
*
* POLICY1,POLICY2(arg1,arg2,...,..,argN),POLICY3,...,POLICYN
*
* Each POLICY name specifies a way to sort at a particular level. Obviously,
* the policy names may not contain commas. Similarly, arg1..argN are arguments
* to the policies. Different policies, just to be confusing, may implement
* different handling of their arguments.
*
* If this ever gets totally out of control, it may be worthwhile to write a
* routine allowing other modules to register parsers for an individual policy.
* Right now I don't think this is necessary.
