Create a exception to thow when Options not exists

Browse Source 
When the user try to get a option that not exist, cxxopt library
throw a std::domain_error, that make a segfaults. See #185.

On this PR I create a new Exception class from OptionParseException
that is throw when this situation occur. This avoid the SegFaults
error.
