Subject: mutator now accesses the diagnostics printed out by clang and adds
 them to the report. for the time being they are all tagged ClangDiag, later
 to be changed to their corresponding misra rule number. most of those
 warnings are have nothing to do with misra so they will be omitted later on.
 I'm supposed to be on a break...
