HOHMANN2002_PROCESS - Process input signal by filterbank object

Usage:

[outsig, obj] = hohmann2002_process(obj, insig);

`obj`	An object created within the HOHMANN2002 filterbank framework by one of the following funtions: hohmann2002, hohmann2002_filter, hohmann2002_delay, hohmann2002_synth, hohmann2002_mixer.
`insig`	Input signal to be processed [time channels].

`outsig`	A matrix containing the processed output signals [time channels]. The columns correspond to the filter bands.
`obj`	The original object with updated filter states.

hohmann2002_process applies the processing given by obj retrieved from the HOHMANN2002 filterbank framework to the input signal.
