One To N and N To One

This "library" demonstrates converting multi-dimensional coordinates to one-dimensional coordinates (and back), up to 4 dimensions. If you examine the source, it should become apparent how to apply this to more dimensions.

Note the Makefile only creates the UnitTests and the unit testing library is added as a git submodule (so you need to do git submodule update --init to get the unit testing framework).

Notes for those who may be confused

x_width refers to the size of the first dimension of the array. So if it is equivalent to 10, then this means that the first dimension contains values from 0-9 inclusive. Thus, a "width" is required for each of the n-1 dimensions to correctly calculate the required indices.
