Extension of the tracers management.

The tracers files can be:

1) "traceur.def": old format, with:

  • the number of tracers on the first line
  • one line for each tracer: <tracer name> <hadv> <vadv> [<parent name>]

2) "tracer.def": new format with one section each model component.
3) "tracer_<name>.def": new format with a single section.

The formats 2 and 3 reading is driven by the "type_trac" key, which can be a

coma-separated list of components.

  • Format 2: read the sections from the "tracer.def" file.
  • format 3: read one section each "tracer_<section name>.def" file.
  • the first line of a section is "&<section name>
  • the other lines start with a tracer name followed by <key>=<val> pairs.
  • the "default" tracer name is reserved ; the other tracers of the section inherit its <key>=<val>, except for the keys that are redefined locally.

This format helps keeping the tracers files compact, thanks to the "default"
special tracer and the three levels of factorization:

  • on the tracers names: a tracer name can be a coma-separated list of tracers => all the tracers of the list have the same <key>=<val> properties
  • on the parents names: the value of the "parent" property can be a coma-separated list of tracers => only possible for geographic tagging tracers
  • on the phases: the property "phases" is [g](l][s] (gas/liquid/solid)

Read information is stored in the vector "tracers(:)", of derived type "tra".

"isotopes_params.def" is a similar file, with one section each isotopes family.
It contains a database of isotopes properties ; if there are second generation
tracers (isotopes), the corresponding sections are read.

Read information is stored in the vector "isotopes(:)", of derived type "iso".

The "getKey" function helps to get the values of the parameters stored in
"tracers" or "isotopes".
