*) Removed hard-wired limits on numbers of species and reactions, by
use of linked lists to replace arrays reaction, reaction.s, and
species.  Code runs as fast or possbibly a bit faster.  Changes
principally in rxnparse() and derivs() and wr_header().  The add_node
functions are more complex than minimally necessary, in order to put
reactions in proper order (FIFO) for easy retrieval in wr_header().

*) Removed dependence on globals, except for passing of RXN *reaction
between main() and derivs(). No way to avoid this.  Num_reactions is no
longer needed (used once for output of its value in wr_header()).

*) A bit more code cleanup.

*) Should comment code -- explain the lsoda() variables defined in
main() and set in initial().
