(was: So having tested this there are a couple of changes needed to make it work properly. I've attached a new version of the patch that works. Can this be committed? or does it need a new jira?)

> Inorder to ease migration from CqlPagingRecordReader to CqlRecordReader, it would be helpful if CRR input_cql defaulted to a select statement that would mirror the behavior of CPRR.
> For example for a give table with partition key `((x,y,z),c1,c2)`
> It would automatically generate
> {code}
> input_cql = SELECT * FROM ks.tab WHERE token(x,y,z) > ? AND token (x,y,z) <= ? 
> {code}
