  and add tables
- Make each ICNTRL value its own subsection

docs/source/tech_info/06_info_for_kpp_developers.rst
- Added "mcm" to the list of C-I tests

docs/source/using_kpp/04_input_for_kpp.rst
- Updated ICNTRL(15) thru ICNTRL(20)
- Now make RCNTRL subsections instead of options
- Edited RCNTRL descriptions for clarity

docs/source/using_kpp/05_output_from_kpp.rst
- Now make ISTATUS and RSTATUS subsections instead of options
- Edited descriptions for clarity

.ci-pipelines/build-testing.yml
- Updated to use the ubuntu-24.04 container instead of the
  ubuntu-20.04 container.  The ubuntu-20.04 container will
  cease to be supported in April 2025.

docs/requirements.txt
- Updated jinja2 from version 3.1.5 to 3.1.6 to fix a security issue
  that was identified by @dependabot.  Jinja2 is one of the packages
  used to generate ReadTheDocs documentation.

docs/source/using_kpp/04_input_for_kpp.rst
- Use plain text to for the "2 slashes and a space" comment character,
  as :code: or :literal: doesn't seem to work.
- Added note about using Fortran D exponents.

src/scan.l
- Added "dD" to the FLOAT and UFLOAT tokens so that it will parse
  Fortran double-precision exponents properly

CHANGELOG.md
- Updated accordingly

int/feuler.f90
- Return TOUT (the ending time of the integration) to the calling
  program via RSTATUS(1).  This is necessary in order for box models
  with the "general" driver to timestep properly.

models/carbon.def
models/carbon.eqn
models/carbon.spc
- Describe new KPP test model based on the GEOS-Chem carbon gases
  mechanism.  Necessary for implementing C-I tests with the
  Forward Euler integrator.

ci-tests/F90_feuler/F90_feuler.kpp
- KPP file for the F90_feuler C-I test.  Uses the carbon mechanism
  with the Forward Euler (feuler) integrator.

.ci-pipelines/ci-common-defs.sh
- Add "F90_feuler" to the list of C-I tests to be done

docs/source/using_kpp/05_output_from_kpp.rst
- Updated the RSTATUS table to denote that the feuler integrator
  now uses RSTATUS(1)

CHANGELOG.md
- Updated accordingly

This merge brings PR #134 (Allow constants in #INITVALUES to have
Fortran double-precision "d" exponents, by @yantosca) into the
KPP 3.2.1 development stream.

PR #134 adds "dD" to the parser command for the FLOAT and UFLOAT
tokens in src/scan.l to allow for "d" exponents.  Documentation
has been updated accordingly.

This merge brings PR #136 (Return Texit from the Forward Euler
(feuler) integrator and add corresponding C-I test #136 , by @)
into the KPP 3.2.1 development stream.

PR #136 fixes a bug where the Texit (time corresponding to the
computed Y value) was not being returned to the calling program
from the int/feuler.f90 integrator.  This is now returned via
RSTATUS(1), as is the case for other integrators.
