       module tracer_h
       !!------------------------------------------------------------------------------------------------------
       !! Stores data related to physics tracers.
       !!
       !! The module provides additional methods: 
       !!   - indexoftracer : search for the index of a tracer in the global table (tracers_h:noms) by name.
       !!   - nameoftracer  : get the name of tracer from a given index (of the global table).
       !!   - dumptracers   : print the names of all tracers indexes given in argument.
