UDTs creation

It would be great to have a method to create User-Defined-Types:

Continuing discussion on UDT creation integration...

The current proposed implementation has the following call signature for creating a type:

cassanKnex("cassanKnexy")
           .createType("myType")
           .text("textType")
           .list("listType", "text");

Which seems appropriate, what we're missing is a suitable signature for using that type in a createColumnFamily statement; since UUDT's in Cassandra require the frozen keyword I'd prefer something like the following (for standard columns/sets/maps):

var cql = cassanKnex("ks")
    .createColumnFamilyIfNotExists("cf")
    .frozen("uudtType", "myType");
// compiles => CREATE TABLE ks.cf ( uudtType frozen <myType> ) ;

// and
    .frozenSet("uudtTypeSet", "myType");
// compiles => CREATE TABLE ks.cf ( uudtType set<frozen <myType>> ) ;

// and
    .frozenMap("uudtTypeMap", "standardType", "myType");
// compiles => CREATE TABLE ks.cf ( uudtType map<standardType, frozen <myType>> ) ;

I agree
