make_compqid

PURPOSE ^

Makes a vector of "composite question IDs" from given question IDs.

SYNOPSIS ^

function compqid = make_compqid(qids,subqids, num_places);

DESCRIPTION ^

 Makes a vector of "composite question IDs" from given question IDs.

 compqid = make_compqid(qids,subqids)

 Makes a vector of "composite question IDs" from the vectors of question IDs
 and subquestion numbers.

 The format for the composite question ID is question.subquestion

 num_places specifies how many places following the decimal point should be
 used for representing the subquestion ID. When num_places=1, there is a limit
 on 9 subquestions. For num_places=2 there is a limit of 99, etc.  Currently,
 the Ensemble-wide assumption is that num_places = 2.
