Add link to cequel-migrations-rails to README
Point Gemfile to github fork of cassandra-cql
Remove Travis config

Until it's possible to test against a live Cassandra 1.2 instance, no
reason to have it in this branch.
Create and read tables
Extract table creation CQL generation into a TableWriter class

I think this will achieve better parallelism with update statements --
basically a Table is just a model for a table's schema, but it does not
know how to either read itself or write itself.
TableUpdater
Add and remove indexes in table update
Table synchronization

Read the existing schema of a table and compare it to a schema defined
using the table DSL. If possible, update the table with added columns,
changed key names, added/removed indices, and updated storage
properties. If not, raise an error.
Use proper terminology for clustering columns

Instead of non-partition keys.
Type definitions for all types, with specs
Cequel::DataSet compatible with CQL3

In particular, full support for insert/update collection columns; don't
quote column names; support retrieving TTL and timestamp for columns.
DataSet#delete_with private
Gemspec cleanup
Move low-level query builder API into Cequel::Metal module
Move logic out of Schema::Keyspace into classes with responsibility
Cequel::Table handles conversion of type names into Type objects
Auto-syncing of model schema
Store schema columns indexed by name
Some work on properties
