20 Lsode Integrator.

22 @NOTE
23 The macro DOTIME is defined inside Lsode.c. If its value is
24 TRUE, we spew all sorts of time junk. If FALSE we are quiet.
25 Default for this macro is FALSE.
26
27 @NOTE the analytic jacobian routines (state matrix) depend on the
28 assumption that struct var_variable *<--> struct Instance *.
29 Requires:
30 #include <utilities/ascConfig.h>
31 #include <solver/slv_client.h>
32 #include <solver/integrator.h>
