FUNCTION MAKE_BASIS_IMAGES,A,n,m
;+
;B=MAKE_BASIS_IMAGES(A,n,m) constructs the (n,m) basis image
;formed from the unitary matrix A. The image is the
;outer product of columns n and m of the Hermetian
;of A.
;
;A unitary matrix for some common transforms may be
;constructed with the function TRANSFORM_BASIS.
