added ParserError
ECustomError stops Parser alternatives
cosmetics
no real need for that
moving pBinOperator + whitespace types as they were before
added infix and assignment operators
pInteger and pFloat read their native values now
differing between hexadecimal and decimal numbers
maybeP fails in case of a custom error
started reworking Ole.Expression
introduced notCharP and notOneOfP
introduced noneP
the ol' switcheroo! parsers that would have failed upon receiving a ECustomError or continue otherwise will continue when receiving an ENoMatch error or fail otherwise
