TPC-H1 does not compile

[4tXJ7f]

The Scala code generator generates invalid code:

[error] test/gen/tpch1.scala:62: error: could not find implicit value for parameter ring: ddbt.lib.Ring[(Double, Double, Double, Double, Double, Double, Double, Long)]
[error]     val agg1 = M3Map.temp[(String,String),(Double,Double,Double,Double,Double,Double,Double,Long)]()
[error]                                                                                                   ^
[error] test/gen/tpch1.scala:134: error: could not find implicit value for parameter ring: ddbt.lib.Ring[(Double, Double, Double, Double, Double, Double, Double, Long)]
[error]     val agg2 = M3Map.temp[(String,String),(Double,Double,Double,Double,Double,Double,Double,Long)]()

This happens because the code generator does not use the custom tuples yet for temporary maps.
