Detailed Description

FxFxFileReader is an base class to be used for objects which reads event files from matrix element generators.

It inherits from FxFxReader and extends it by defining a file handle to be read from, which is opened and closed by the open() and close() functions. Note that the file handle is a standard C filehandle and not a C++ stream. This is because there is no standard way in C++ to connect a pipe to a stream for reading eg. gzipped files. This class is able to read plain event files conforming to the Les Houches Event File accord.
