Generate Biorthonormal QMF Filter Pairs
[qmf,dqmf] = MakeBSFilter(Type,Par)
string, one of: 'Triangle', 'Interpolating', 'Deslauriers' (the two are same), 'Average-Interpolating', 'CDF' (spline biorthogonal filters in Daubechies's book), 'Villasenor' (Villasenor's 5 best biorthogonal filters)
integer list, e.g. if Type ='Deslauriers', Par=3 specifies Deslauriers-Dubuc filter, polynomial degree 3
quadrature mirror filter (odd length, symmetric)
dual quadrature mirror filter (odd length, symmetric)
