* Avoids boot time mutation of REGISTER constant * Allows to define project specific expression parsing * Avoids custom (slow) serialization of Expression objects speeding up reporter / killer IPC * Improve specification * Improve integration API as it now finally references an object the config * Allow reproduction of syntax from Expression#syntax * Allow instantiation of Expresssion objects without generating the syntax, much nicer for most specs & internal code, avoids generating a string to parse it into an expression * Fix LSP violation in Mutant::Matcher namespace
