To avoid the following Octave error:
operator =: no conversion for assignment of 'float complex matrix' to
indexed 'complex matrix'
Fixed MEX and OCT template helpers

Handling of cell arrays was incorrect.
Random filters used in test_frames are now forced produce a nice cond. num.

... and removed them from blockproc/Contents
offline mode in block no longer require fs
Disabled usage of filterbank frames with segola block transform handling

It is not reliable enough.
More sanity checks in blockana and blocksyn
Disabled 'valid' option in helper fwt routines.
Avoiding warning: implicit conversion from matrix to sq_string in Octave
Splitting of framecoef2tf

framecoef2tf now handles only frames which rectangular coefficient
layout. Other frames were moved to framecoef2tfplot.
Minor fixes
Nicer cond number of test cases in test_spread
