In general we try to stay away from naming things after specific types of tables (like OTU table) since the biom-format can handle many different table types. In the python code we name the general BIOM table ```Table```, which is comprised of ```Data``` (i.e. the data matrix, or observation counts), ```SampleIds```, ```ObservationIds```, ```SampleMetadata```, and ```ObservationMetadata```. Thus, we try to keep our names pretty general; a BIOM table contains information about *samples* and *observations* instead of *samples* and *OTUs*.

This comment applies not only to this section but several other places in the code that reference OTU table-specific stuff.
