/**
* FxFxReader is an abstract base class to be used for objects
* which reads event files or streams from matrix element
* generators. Derived classes must at least implement the open() and
* doReadEvent() methods to read in information about the whole run into
* the HEPRUP variable and next event into the HEPEUP variable
* respectively. Also the close() function to close the file or stream
* read must be implemented. Although these functions are named as if
* we are reading from event files, they could just as well implement
* the actual generation of events.
*
* After filling the HEPRUP and HEPEUP variables, which are protected
* and easily accesible from the sub-class, this base class will then
* be responsible for transforming this data to the ThePEG Event
* record in the getEvent() method. <code>FxFxReader</code>s can
* only be used inside FxFxEventHandler objects.
*
* In the initialization the virtual open() and scan() functions are
* called. Here the derived class must provide the information about
* the processes in the variables corresponding to the HEPRUP common
* block. Note that the IDWTUP is required to be +/- 1, and sub
* classes are required to change the information accordingly to
* ensure the correct corss section sampling. Note also that the
* controlling FxFxEventHandler may choose to generate weighted
* events even if IDWTUP is 1.
*
* Note that the information given per process in e.g. the XSECUP and
* XMAXUP vectors is not used by the FxFxEventHandler and by
* default the FxFxReader is not assumed to be able to actively
* choose between the sub-processes. Instead, the
* FxFxEventHandler can handle several FxFxReader objects
* and choose between them. However, a sub-class of FxFxReader
* may set the flag isActive, in which case it is assumed to be able
* to select between its sub-processes itself.
*
* The FxFxReader may be assigned a number ReweightBase objects
* which either completely reweights the events produced (in the
* reweights vector), or only biases the selection without influencing
* the cross section (in the preweights vector). Note that it is the
* responsibility of a sub-class to call the reweight() function and
* multiply the weight according to its return value (typically done
* in the readEvent() function).
*
