C Contains passive tracer modules and associated macros

CEOP

      use ptracers_dyn_state_mod
      use ptracers_dyn_state_data_mod

C     This macro allows the second-order-moment member of the ptracers
C     internal state data structure to be used like an simple array. 
C     Names are chosen such that macro expansion does not increase
C     line length
