class AliTPCAltroEmulator: public TNamed

Class for emulation of the ALTRO chip (Altro digital Chain) in C++
Author: Roland Bramm

NOTE: This class has been modified to be conform with the coding conventions of the
ALICE Off-line Project. Keywords for setting the mode of BSC1 were modified
and are shown in the header file ...
