Known m@cortex bugs and quirks

.nex file handling: retrieval of spike data appears to be consistent with NBP's routines. Handling of analog data from .nex files, however, has not been tested yet.
giucode.def: the 'collect_spikes' parameter in the [cortex] section is not functional
the @spix spike matrix does not support "short" trials (with NaN-padded spike trains) the way @cortex does
it is only possible to return a single-key @key object from an exising multi-key object. In other words, given the @key object k, sk=k(3) is legal, while mk=k(3:5) is not; this is something I'd like to change
factors can only be added to a live @key object, and there is currently no way to include factors in a source key file.

this list is destined to grow. Please contribute by sending me bug reports...
