Calculates the Riemannian shape distance $$ between two
configurationsriemdist(x, y)x{k x m matrix (or complex k-vector for 2D data)
where k = number of landmarks and m = no of dimensions}
y{k x m matrix (or complex k-vector for 2D data)}The Riemannian shape distance rho between the two configurations.
Note 0 <= rho="" <="pi/2
