@baierd Should I still split up the option for parsing/dumping? Or is this fine with you? |

Hello,
this PR extends the Tokenizer to recognize all commands from the SMTLIB standard. We also add a configuration option
parser.illegalInputto let the user decide how to handle illegal commands. Currently, we simply skip over unrecognized/uninteresting commands while parsing. This can hide potential bugs or lead to confusing error messages. With the new option, skipping is still the default behavior. However, it's also possible to log illegal commands or abort the parse entirely by setting the option to a different valueThe idea is to eventually make the Tokenizer strict and always throw an exception. However, we may still have to add more non-standard commands first
