Torus Datatype
A Torus is a geometric surface that can be represented by a doughnut: from any point on the surface, moving up/down or left/right will eventually lead you back to where you started, to continue on indefinitely. This has the capability of representing an infinite space with a finite amount of material.
The Torus datatype provides this functionality by wrapping the raw TrueData, and using (one-based) modular arithmetic to extend its space indefinitely. The subscript implementation is meant to be intuitive and match MATLAB's behavior of the builtin datatypes as closely as possible.
An easy example is the need to have the pattern [1 2 3] repeated end-over-end in a vector of length 20. A somewhat general solution might look like the following:
x = 1:3; % original data
n = 20;
y = repmat(x,1,ceil(n/length(x))); % make a new vector that is too big
y(1:n) % pick off the first n elements
Doing this with a Torus would be much more intuitive and efficient:
T = Torus(1:3);
T(1:20)
