This static method returns a new identity matrix of the requested size. The first overload takes a single integer
*n* and returns an n by n matrix. The second overload takes two integers (n,d) and returns a Matrix object with
*n* rows and *d* columns.

An identity matrix is an {m, n} matrix with all values where m != n are zero and all values where m == n are one. For example:

var identity = Matrix.Identity(3); // identity is // {{1, 0, 0}, // {0, 1, 0}, // {0, 0, 1}} // // notice that all values are zero except identity[0,0], identity[1,1] and identity[2,2].
