Forward Median Interpolationg Pyramid Transform
wc = FMIPT(x,L,D)
1-d signal; length(x) = 3^J
Coarsest Level of V_0; L << J
degree of polynomial used in median interpolation, 0 or 2.
1-d median transform of x (twice as long as wc, although the transform is only about 50// expansionist)
The MIPT coefficients are "L^2 normalized"
