//
// SBT task for slick code generation for a live database
// ======================================================
// 
// This sbt task will generate slick scala classes to match your (MySQL) database schema,
// which will allow you to use the database through slick, in your scala application. 
//
// Usage:  Review all ? symbols and comments below, to adapt to your system. Embed in build.sbt. 
//         Make sure the database is up. Run: sbt slickGenerate
//         In your scala application, import the resulting scala file
