Title: Added support for the expireAfterSeconds option for an Index

This option allows documents to expire after a given amount of seconds.

The `expireAfterSeconds` option may optionally be added onto an index
for a field containing a 'Date' BSON typed entry. For more information
regarding this option please see the following entry on the MongoDB
website: http://docs.mongodb.org/manual/tutorial/expire-data/

Documentation update will follow after this PR
