gram_matrix(matrix)
Compute the Gram matrix of input 2D matrix.
In Linear Algebra the Gram matrix G of a set of vectors (u_1, u_2, .. , u_n) is the matrix of dot products, whose entries are:
G_{ij} = u^T_i * u_j = numpy.dot(u_i, u_j) OR GA = A * A^T
Uses tenforflow to compute the Gram matrix of the input 2D matrix.
