> Currently, our engine supports matrix-vector binary operations.  For example, we make
use of broadcasting to allow for binary operations between matrices and vectors that have
a common size in each the row or column dimension.  However, we do not  support vector-matrix
binary operations.
> Works correctly --> op(matrix, vector):
> {code}
> a = rand(rows=4, cols=16)
> b = rand(rows=1, cols=16)
> out = a * b
> print(toString(out))
> {code}
> Fails --> op(vector, matrix):
> {code}
> a = rand(rows=4, cols=16)
> b = rand(rows=1, cols=16)
> out = b * a
> print(toString(out))
> {code}
