// Description...: A simple realization of an inf. vector.
// Comments......: A perhaps better implementation than a vector would
//                 be to keep a pointer to a decision table and an
//                 object index. Then, one get the masking stuff for
//                 free, in addition to not having to copy data back and
//                 forth. On the downside, there'd be data consistency
//                 issues and I/O..
