@fhueske I think we should keep the methods as they currently are. I
renamed them to "nextNumericString"/"nextNumericStringEndPos" and added a
explanation what a numeric string is. You are right they don't do much numeric
at the moment but only the numeric classes will use it. Furthermore, the error
states and exceptions are numeric. E.g. if we don't do the whitespace checking
in `nextNumericString` we also need to return the position instead of the
string.
