Subject: Store wave, bin_info, and wave_info separately in WaveRecord.
X-Git-Tag: v0.2~29
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=8574937ba2e351820597b6c100bb48af1822de3b;p=igor.git

Store wave, bin_info, and wave_info separately in WaveRecord.

This makes more sense than storing them as a tuple.

Also, use wave_record.wave_info['bname'] as the name for storing the
wave in the filesystem view returned by packed.load.
