R biom package v0.3.8, the version released on [CRAN](http://cran.r-project.org/web/packages/biom/index.html)

Minor changes only (mostly documentation) to satisfy CRAN submission requirements and a stability suggestion from one of the CRAN maintainers. Very minor.

Also included the `biom_0.3.8.tar.gz` compressed version, which makes an easily available (and installable) snapshot of the first beta release.

See [biom on CRAN](http://cran.r-project.org/web/packages/biom/index.html) for status updates and dependency information. The Mac OS X binary is already available at the time of this pull request. The Windows binary has already been built (according to auto-generated correspondence from CRAN), and should also appear soon. 

### Installation
For binary installation from within an R session and internet access:

```S
install.packages("biom")
```

If binary is not (yet) available on your platform, can always install "from source":
```S
install.packages("biom", type="source")
```
