Adding Erlang unit tests.

To run these tests:

    $ git clone git://github.com/ngerakines/etap.git
    $ cd etap
    $ sudo make install
    $ cd /path/to/couchdb
    $ ./bootstrap && ./configure && make check

So far I've worked through most of couch_file.erl, couch_btree.erl, and couch_doc.erl. Tomorrow I'll be adding coverage reporting so that we can see what code we're actually testing.
