C Structure to define trigger  -
C structure.  Each trigger condition is composed of set of "andor" terms
C which are required or vetoed.  See ANDOR_TERM_STRUCT.INC.  Each trigger
C consists of a name and bit number, array of andor terms and polarities
C to be used for the trigger (to be defined by the user), and the state
C of the trigger and accounting information filled by the simulation
