Some more work on comp_filterbank etc. test_erbfilters now passes for the filterbankdual. filterbanktight has probably a bug in it.

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.

erbfilters can now create whole-frequency range filterbanks. Corrected the scaling in erbfilters to correctly account for the channel downsampling.

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.

warped filters are now handled efficiently, and gives perfect reconstruction

Fixed bug #6, demo_audioshrink now works again. Removed wilgrouplasso. Better help in erbfilters. Changed idgt and idgtreal examples to use the dual window for analysis.

more work on fractional sampling in filterbanks, reconstruction does still not work
