// Event class

// Event class represents the events which are going to be simulated on the runway
// A generic event does not have any meaning. So, this is an abstract class.
// It has got two pure virtual functions. You cannot instantitate this class. The 
// functions doEvent and draw will be implemented by the derived classes
