The CoordArrays class provides a way to describe X/Y coordinate data to the HLU library.

The CoordArrays object uses two arrays to do this: the caXArray and the caYArray. The caXCast and caYCast resources are used to determine which dimension of the caXArray and caYArray should be recognized as vectors, and which dimension should be element of the vectors.
The Min and Max resources are computed if they are not set explicitly. If the caXArray or caYArray resources are reset to new values, the Min and Max values are recomputed unless the Min and Max values have been explicitly set by the user. If these resources are ever set, the programmer/user is taking responsibility for updating them if they need to be updated.
