I think we just need to teach cql.py the new-in-0.8.1 types.  (CASSANDRA-2530)

> I'm just getting started with CQL, and decided to do a simple test create/insert/select
thing to check that everything was working.  Most everything seems to work, but it appears
that double/floats do not work properly.  Here's what I did:
> test.cql
> --------------------------
> CREATE KEYSPACE test with strategy_class = 'SimpleStrategy' and strategy_options:replication_factor=1;
> USE test;
> CREATE COLUMNFAMILY testvals (
>     key varchar PRIMARY KEY,
>     value float
>    );
> INSERT INTO testvals (key,value) VALUES ('k1',341.32355);
> SELECT key, value FROM testvals;
> --------------------------
> The output is this:
> cqlsh localhost < scripts/test.cql
>  key |    value |
>   k1 | @uU-B??? |
> Same thing happens when I do value double.  I also tried to do this from the python driver,
gives the same weirdness:
> In [2]: import cql
> In [3]: con = cql.connect("localhost",keyspace="test")
> In [4]: cursor = con.cursor()
> In [5]: cursor.execute("SELECT * from testvals")
> Out[5]: True
> In [6]: for r in cursor: print r
>    ...: 
> [u'k1', '?\xf8\x00\x00\x00\x00\x00\x00']
