function PlotSynthesisTable(TfType,atomlist,n,D,scal,tit)
// PlotSynthesisTable -- Display entries in atomlist as WP or CP table
//  Usage
//    MakeSynthesisTable(TFType,atomic,n,D,scal,ttl)
//  Inputs
//    TFType	  string, 'WP' or 'CP' indicating type of atom
//    atomic	  atoms from wavelet packet or cosine packet table
//    n,D      usual packet table parameters (from which atoms are taken)
//    scal     optional scaling factor (0 => autoscale)
//    ttl      optional title
//
//  Side Effects
//   spike plot of coefficients in synthesis table
//
