block_interface now completely in C, saving some precious computing time for the bloc. proc. framework.
dwilt and wmdct are now supported in the block. proc. fr.
New checks if dual window is FIR (dgt,dwilt,..).

Converted wavelet filters to a format of firfilter.
Moved some stuff from comp_filterbank to comp_filterbank_pre.
Cleaned wavelets dir.
Added conversion function wfbt2filterbank which creates equivalent plain filterbank from a arbitrary filterbank tree.
comp_transferfunction now checks for existence of additional fields of the input struct. Mandatory fields are now .h and .offset for the FIR filter and .H and .foff for band-limited filters.

added missing semicolons to avoid Octave warnings; added 'redmul' option to erbfilters. By default it generates the highest possible downsampling rate while keeping the system painless.
