* Zorbage delineates many data types walled off in designations like NumberMember or
* Vector/RModuleMember, MatrixMember, and TensorProductMember. However in mathematical
* terms each smaller type (say Number) can be treated as a special case of a higher
* level type. For instance a Number is the same as a 1-element vector or the same as
* a 1x1 shaped matrix or a 1x1x1... shaped tensor. Given these relationships we define
* bridge classes that allow elements of one type (vector for instance) to be passed
* as another (a rank 1 tensor for instance). There are numerous bridge classes and
* they will be detailed below.
