using Statement instead of Select 

It was not possible to call cassandraTemplate.select() method after creating a Statement via QueryBuilder, as it takes only Select as an argument

//example
val select: Statement = QueryBuilder.select().all().from(tableName).setFetchSize(maxResults)

Statement appears as a Base Class for Select and others,  I havent look much why cassandraTemplate was tailored specifically for Select, but the tests are passing with Statement so hopefully this change make sense.
