cql 1.4.0

Cassandra Query Language driver

A Python driver for CQL that adheres to py-dbapi v2
(PEP249, Python Database API Specification v2.0: http://www.python.org/dev/peps/pep-0249/).

Standard use:
>> import cql
>> con = cql.connect(host, port, keyspace)
>> cursor = con.cursor()
>> cursor.execute("CQL QUERY", dict(kw='Foo', kw2='Bar, etc...))

- cursor.description # None initially, list of N tuples that represent
the N columns in a row after an execute. Only
contains type and name info, not values.
- cursor.rowcount # -1 initially, N after an execute
- cursor.arraysize # variable size of a fetchmany call
- cursor.fetchone() # returns a single row
- cursor.fetchmany() # returns self.arraysize # of rows
- cursor.fetchall() # returns all rows, don't do this.

>> cursor.execute("ANOTHER QUERY", **more_kwargs)
>> for row in cursor: # Iteration is equivalent to lots of fetchone() calls
>> doRowMagic(row)

>> cursor.close()
>> con.close()

Query substitution:
- Use named parameters and a dictionary of names and values.
e.g. execute("SELECT * FROM CF WHERE name=:name", {"name": "Foo"})
