Provides error report capability to other owner components by encapsulating user-specified ErrorHandler and exposing utlity methods. 

This class also wraps SAXException to a RuntimeException
so that the exception thrown inside the error handler
can abort the process.

At the end of the day, we need to know if there was any error.
So it is important that all the error messages go through this
object. This is done by hiding the errorHandler from the rest
of the components.
