         TC_kmodint - utility used to parse kinetic models
         ----------------------------------------------
  
         Usage: TC_kmodint_(char *mechfile,int *lmech,char *thermofile,int *lthrm)
         <ul>
         <li> mechfile: file containing the kinetic model
         <li> lmech: length of the character string above (introduced to
                      enable passing of character strings from Fortran to C)
         <li> thermofile: file containing thermodynamic properties (NASA
     polynomials) <li> lmech: length of the character string thermofile
     (introduced to enable passing of character strings from Fortran to C)
         </ul>
         Output:
         <ul>
         <li>kmod.out - ascii file containing kinetic model info formatted
                        for visual inspection
         <li>kmod.list - ascii file containing unformatted data for tchem
         </ul>
  
         <b> Brief description of kinetic model input format  </b>
         ( For a detailed description of the kinetic model format and keywords
     see: Robert J. Kee, Fran M. Rupley, Ellen Meeks, and James A. Miller
         "CHEMKIN-III:A Fortran Chemical Kinetics Package for the Analysis of
     Gas-phase Chemical and Pllasma Kinetics", Sandia Report, SAND96-8216, (1996)
     )
  
         \b Elements :
                   - Number of elements is "unlimited"
                   - Elements not present in file periodictable.dat must
                       be followed by their atomic weight, e.g.
                       N+ /14.0010/
                   - Element names are one or two characters long
                   - Any duplicate listing of an element is ignored
  
         \b Species :
                   - Number of species is "unlimited"
                   - Species need to be formed only of elements declared in the
                       list of elements
                   - Species names are "LENGTHOFSPECNAME" characters long
                   - Any duplicate listing of an species is ignored
                   - A species can contain at most "NUMBEROFELEMINSPEC"
                       distinct elements
  
         <b> Thermodynamic data </b>:
                   - Data can be provided in the kinetic model file and/or
                       the thermodynamic file;
                   - Currently, only NASA polynomials are accepted; two (2)
                       temperature intervals
                   - Data needs to be provided for all species
  
         \b Reactions :
                   - Number of reactions is "unlimited"
                   - Pre-exponential factor units MOLES or MOLECULES;
                       default is MOLES
                   - Activation energy units: CAL/MOLE, KCAL/MOLE,
                       JOULES/MOLE, KJOULES/MOLE, KELVINS, eVOLTS ;
                       default is CAL/MOLE. Units are converted to KELVINS
                       if necessary; conversion factors are based on
                       NIST data as of July 2007
                   - maximum number of reactants or products is "NSPECREACMAX"
                   - reactants and products are separated by "<=>" or "="
                       (reversible reactions) or "=>" (irreversible reactions)
                   - species are separated by "+"
                   - three Arrhenius parameters should be given for each reaction
                       in the order : pre-exponential factor, temperature
     exponent, activation energy
                   - reaction lines that are too long can be split on
                       several lines using the character "&" at the end of each
                       line
  
         <b> Auxiliary reaction info </b> :
                   - Auxiliary data needs to be provided immediately
                       following the reaction to which it corresponds to
                   - Any keywords except DUPLICATE,MOME, and XSMI need
                       to be followed by numerical values enclosed
                       between "/"
                   - Duplicate reactions \n
                         \b DUPLICATE
                   - third-body efficiencies for reactions containing
                       "+M" (not "(+M)" ) as a reactant and/or product:\n
                          speciesname /value/
                       the maximum number of third-body efficiencies is
                       given by "NTHRDBMAX"
                   - pressure-dependent reaction are signaled by the
                       inclusion of "(+M)" as a reactant and/or product
                       or by the inclusion of a particular species, e.g.
                       "(+H2)" as a reactant and/or product. Some of
                       the following parameters are required to describe
                       the pressure dependency:\n
                         \b LOW  /value1 value2 value3/\n
                         \b HIGH /value1 value2 value3/\n
                         \b TROE /value1 value2 value3 value4/ (if value4 is
     ommited then the corresponding term is ommited in the corresponding Troe
     formulation) \n \b SRI  /value1 value2 value3 value4 value5/ (if value4 and
     value5 are ommited then value4=1.0, value5=0.0)
                   - Landau-Teller reactions\n
                         \b LT /value1 value2/ for the forward rate \n
                         \b RLT /value1 value2/ for the reverse rate. If REV is
                             given then RLT is mandatory; if not then RLT is
                             optional
                   - Additional rate fit expressions: \n
                         \b JAN /value1 value2 ... value9/\n
                         \b FIT1 /value1 value2 value3 value4/
                   - Radiation wavelength for reactions containing HV as
                       a reactant and/or product \n
                         \b HV /value1/
                   - Reaction rate dependence on a particular species
                       temperature\n
                         \b TDEP /speciename/
                              <ul>
                               <li> Energy loss parameter
                              </ul>
                         \b EXCI /value1/
                   - Plasma (Ion)  momentum-transfer collision frequency\n
                         \b MOME (\b XSMI)
                   - Reverse reaction Arrhenius parameters\n
                         \b REV /value1 value2 value3/
                   - Change reaction order parameters\n
                         \b FORD /specname value1/ (for forward rate)\n
                         \b RORD /specname value1/ (for reverse rate)
                   - Reaction units for reactions with units different
                       than most of the other reactions\n
                         \b UNITS /unit1 unit2/ \n(the number of keywords between
                         "//" can be one if only one set of units is changed
                         or two if both pre-exponential factor and
                         activation energy are to be modified)
