Next generation of macros
Implements SIP 16: Self-cleaning macros: http://bit.ly/wjjXTZ Features: * Macro defs * Reification * Type tags * Manifests aliased to type tags * Extended reflection API * Several hundred tests * 1111 changed files Not yet implemented: * Reification of refined types * Expr.value splicing * Named and default macro expansions * Intricacies of interaction between macros and implicits * Emission of debug information for macros (compliant with JSR-45) Dedicated to Yuri Alekseyevich Gagarin
