/**
 * Wrapper around UDT and non-UDT types.
 * 
 * The reason for this interface is that the core API doesn't let us build {@link com.datastax.driver.core.DataType}s representing UDTs, we have to obtain
 * them from the cluster metadata. Since we want to use SchemaBuilder without a Cluster instance, UDT types will be provided via
 * {@link UDTType} instances.
