SUBROUTINE CKCTYP (P, T, Y, ICKWRK, RCKWRK, CDOT, TAU)
Returns the molar creation rates and characteristic destruction
times of the species given pressure, temperature(s) and mass
fractions.

INPUT
P         - Real scalar, pressure.
               cgs units, dynes/cm**2
T(*)      - Real array, temperature(s); dimension is determined by
            the application program to be the total number of
            species temperatures, nominally 1.
               cgs units, K
Y(*)      - Real array, mass fractions of the mixture;
            dimension at least KK, the total species count.
ICKWRK(*) - Integer workspace array; dimension at least LENICK.
RCKWRK(*) - Real    workspace array; dimension at least LENRCK.

OUTPUT
CDOT(*)   - Real array, chemical creation rates of the species;
            dimension at least KK, the total species count.
               cgs units, mole/(cm**3*sec)
TAU(*)    - Real array, characteristic destruction times of the
            species;
            dimension at least KK, the total species count.
               cgs units, sec
