— forked from skinner/NamespacedCodegen.scala
The available code from @skinner was for Slick 2.0(not using scala 2.11). From scala 2.11, some of the core libraries were moved out. So the code will not work with 2.11 scala. Also, added column name customization and case class/mapping class name customization as well.
