vendoring couchrest session store for development
0.4.0 has not been released yet. But travis needs it to run. So i vendor it for now. Will remove it again when the build is getting stable.

+# CouchRest::Session::Store #
+
+A simple session store based on CouchRest Model.
+
+## Setup ##
+
+`CouchRest::Session::Store` will automatically pick up the config/couch.yml
+file used by CouchRest Model.
+
+Cleaning up sessions requires a design document in the sessions database that
+enables querying by expiry. See `design/Session.json` for an example. This
+design document is loaded for tests, but you will need to load it on your own
+in a production environment. For example:
+
+ curl -X PUT username:password@localhost:5984/couchrest_sessions/_design/Session --data @design/Session.json
+
+## Options ##
+
+* marshal_data: (_defaults true_) - if set to false session data will be stored
+ directly in the couch document. Otherwise it's marshalled and base64 encoded
+ to enable restoring ruby data structures.
+* database: database to use combined with config prefix and suffix
+* expire_after: lifetime of a session in seconds.
+
+## Dynamic Databases ##
+
+This gem also includes the module `CouchRest::Model::DatabaseMethod`, which
+allow a Model to dynamically choose what database to use.
+
+An example of specifying database dynamically:
+
+ class Token < CouchRest::Model::Base
+ include CouchRest::Model::DatabaseMethod
+
+ use_database_method :database_name
+
+ def self.database_name
+ time = Time.now.utc
+ "tokens_#{time.year}_#{time.month}"
+ end
+ end
+
+A couple notes:
+
+Once you include `CouchRest::Model::DatabaseMethod`, the database is no longer
+automatically created. In this example, you would need to run
+`Token.database.create!` or `Token.database!` in order to create the database.
+
+The symbol passed to `database_method` must match the name of a class method,
+but if there is also an instance method with the same name then this instance
+method will be called when appropriate. To state the obvious, tread lightly:
+there be dragons when generating database names that depend on properties of
+the instance.
+
+## Database Rotation ##
+
+The module `CouchRest::Model::Rotation` can be included in a Model in
+order to use dynamic databases to perform database rotation.
+
+CouchDB is not good for ephemeral data because old documents are never really
+deleted: when you deleted a document, it just appends a new revision. The bulk
+of the old data is not stored, but it does store a record for each doc id and
+revision id for the document. In the case of ephemeral data, like tokens,
+sessions, or statistics, this will quickly bloat the database with a ton of
+useless deleted documents. The proper solution is to rotate the databases:
+create a new one regularly and delete the old one entirely. This will allow
+you to recover the storage space.
+
+A better solution might be to just use a different database for all
+ephemeral data, like MariaDB or Redis. But, if you really want to use CouchDB, this
+is how you can do it.
+
+An example of specifying database rotation:
+
+ class Token < CouchRest::Model::Base
+ include CouchRest::Model::Rotation
+
+ rotate_database 'tokens', :every => 30.days
+ end
+
+Then, in a task triggered by a cron job:
+
+ CouchRest::Model::Base.configure do |conf|
+ conf.environment = Rails.env
+ conf.connection_config_file = File.join(Rails.root, 'config', 'couchdb.admin.yml')
+ end
+ Token.rotate_database_now(:window => 1.day)
+
+Or perhaps:
+
+ Rails.application.eager_load!
+ CouchRest::Model::Rotation.descendants.each do |model|
+ model.rotate_database_now
+ end
+
+The `:window` argument to `rotate_database_now` specifies how far in advance we
+should create the new database (default 1.day). For ideal behavior, this value
+should be GREATER than or equal to the frequency with which the cron job is
+run. For example, if the cron job is run every hour, the argument can be
+`1.hour`, `2.hours`, `1.day`, but not `20.minutes`.
+
+The method `rotate_database_now` will do nothing if the database has already
+been rotated. Otherwise, as needed, it will create the new database, create
+the design documents, set up replication between the old and new databases,
+and delete the old database (once it is not used anymore).
+
+These actions will require admin access, so if your application normally runs
+without admin rights you will need specify a different configuration for
+CouchRest::Model before `rotate_database_now` is called.
+
+Known issues:
+
+* If you change the rotation period, there will be a break in the rotation
+ (old documents will not get replicated to the new rotated db) and the old db
+ will not get automatically deleted.
+
+* Calling `Model.database.delete!` will not necessarily remove all the
+ relevant databases because of the way prior and future databases are kept
+ for the 'window' period.
+
+## Changes ##
+
+0.3.0
+
+* Added support for dynamic and rotating databases.
+
+0.2.4
+
+* Do not crash if can't connect to CouchDB
+
+0.2.3
+
+* Better retry and conflict catching.d \ No newline at end of file
