* Add Mutant::AST namespace to hold all AST related data / helpers. * Mutant::AST will be externalized into an ast-meta gem that can be shared with unparser for deduplication. * Over the time the mutators itself will not need to deal with semantic analysis of the AST anymore by themselves. * Move AST analysis for send nodes to AST::Meta * Fix #209
