Merge pull request #2 from sosalla/master

Brought get_contact up to R style guide standard.
Removed the `siteid` variable from `get_site`, the API does not accept that as a parameter.  Fixed bug #91 in `get_download` by adding `drop=F` to the count subsetting.
Merge pull request #3 from sosalla/master

Bringing code up to Google's R Style Guide standards.  See standards here: https://google-styleguide.googlecode.com/svn/trunk/Rguide.xml
Added `compile_downloads` to the package to provide methods to convert a list of downloaded sites to a single large `data.frame`.  Renamed `compile_list`, changing it to `compile_taxa` so it is clearer.  Fixed a small problem in `get_download` so that it doesn't balk at empty datasets.

TODO:  Develop an internal function in `get_download` so that it can download from a list of datasets.
Formatting changes to meet Google R style guide.

Moved the columns of the output from `get_chroncontrol` around so that they make more intuituve sense.  Same column names as before.

Fixed a conflict in `get_contact` that arose from the improved stylings of the code.

Wrote `write_agefile` that will output a file formatted for clam or bacon based on the chron control table exported from the download object.
Merged Luke's style changes.  Resolved some conflicts.

Emergency fix, some brackets were unpaired.
Brought get_taxa up to Google's R style guide.
Brought write_agefile and compile_taxa up to Google's R Style guide standards. Made minor syle guide improvements that I missed the first time around in several other files. Also changed get_datasets to get_dataset in several examples. Ran most of the examples and they seem to be working fine.
