Ideas for KPP 4.0.0

[RolfSander]

Add your ideas for KPP 4.0.0 here. Everything we don't have the time to work on now but may be a nice addition in the future...

Items yet to be done

• Use ICNTRL in tau_leap and gillespie integrators.

• Add RODAS3.1 coefficients to Rosenbrock integrators

• Add Python (wrapper) and Julia as new languages to KPP.

• Have the Fortran90 code create a derived type with global variables.
  (See [FEATURE REQUEST] Save KPP global variables into a derived type object #11)

• Formal uncertainty quantification and propagation through an integration step.

• Add #DEBUG command

• Write input file checker,
  (See Input file checker #95)

Items recently completed

• Replace all BLAS/LAPACK functions (WAXPY, WSCAL, etc.) in integrator files
  (See Replace BLAS functions w/ pure F90 code in integrators #142 and Replace BLAS function WDOT with the Fortran DOT_PRODUCT intrinsic function #143)

• Update obsolete fortran code, e.g., arithmetic IF statements
  (See Replace BLAS function WDOT with the Fortran DOT_PRODUCT intrinsic function #143)

• Delete #WRITE_OPT and WriteOptions() in debug.c.
  (See Remove several more obsolete KPP commands #89)

• Delete #LUMP?
  (See Remove obsolete #LUMP command (and related variables) #88)

• Delete #TRANSPORT and #TRANSPORTALL
  (See Remove obsolete #TRANSPORT and #TRANSPORTALL commands #87)

• Enlarge some limits so that the complete MCM can be used
  (See Fixes to allow using the full MCM #100)

• Use Y instead of C in Update_RCONST()
  (See Add code from #INLINE F90_RCONST_USE at the top of the UPDATE_RCONST subroutine #120 and Add inlined code in the #INLINE F90_RCONST_USE block to the Update_Photo routine #125)

• Migrate C-I tests from Azure Dev Pipelines to GitHub actions
  (See Migrate C-I tests from Azure Dev Pipelines to GitHub actions #138)
