Detailed Description

A class to define index-sets, specifically for subvectors and submatrices.

The interval data-type is not fully developed yet. At the moment, it allows a convenient way to specify subvectors and submatrices. Eventually, I will try to extend it to generalized subsets of the positive integers; it will be possible to select V[[1,3,5..8]], for instance. This is not, however, a high priority. At the moment, interval is constructed as interval(start,end), and is stored as {offset,range}. No error checking.
