Constellation objects accept n-dimensional points. (i.e. n complex numbers correspond to one symbol value.)
Added tests to qa_trellis.py.
Added comments to fsm.h
Added trellis_constellation_metrics_cf. It is equivalent to trellis_metrics_c but it uses the constellation object's calc_metric method. This method is also added here. trellis_metric_type.h is moved to gr_metric_type since constellation object is now dependent on it.
Fixed Makefiles to generate swig_doc.i
Merged upstream from next
Fixed minor bug in fsm.cc for fsms with 1 state.
Use load-extension-global instead of load-extension
trellis_generated.i has to be generated first, befofre we can generate anything else.
Merge branch 'next' into guile-next
