Initial work on dual-tree wavelet transform and wavelet packets
Some more probing
Fixed delay computation in multirate identity filterbanks
Closer to the correct behavior
Sanitizing window format in comp_fourierwindow
Changing phase of modulation in wavelet filters (lowpass -> highpass)
Merge branch 'master' into dual-tree

To get back the fix in nodesMultid
First working version of dual-tree wavelet transform
Fixed typo in function reference in nonu2ufilterbank.m
Work on wfiltdt_oddeven
Fixed bug in comp_ifilterbank.c

Bug was causing seg. fault when mixed (consisting of filters defined by
both imp. resp. and freq. resp.) filterbank was used.
Added function for computing periodic group delay
Fixed typo in demo_imagecompression
New tests for dual-tree wavelet transform
Changing format of output of wfilt_ prefixed functions

To be actually a filterbank
Cleanup in wfbtmanip

And related changes
Finished dual-tree wavelet transform routines
Merge branch 'dual-tree'
backup commit
Merge branch 'master' into workdirbackup
