Fitting the Topt temperature response model

Provides wrapping functions to add to capabilities to 'plantecophys'
(Duursma, 2015, <doi:10.1371/journal.pone.0143346>). Key added capabilities
include temperature responses of mesophyll conductance (gm, gmeso), apparent
Michaelis-Menten constant for rubisco carboxylation in air (Km, Kcair),and
photorespiratory CO2 compensation point (GammaStar) for fitting A-Ci or A-Cc
curves for C3 plants (for temperature responses of gm, Km, & GammaStar, see
Bernacchi et al., 2002, <doi:10.1104/pp.008250>; for theory on fitting A-Ci
or A-Cc curves, see Farquhar et al., 1980; <doi:10.1007/BF00386231>, von
Caemmerer, 2000, ISBN:064306379X; Ethier & Livingston, 2004
<doi:10.1111/j.1365-3040.2004.01140.x>; and Gu et al., 2010,
<doi:10.1111/j.1365-3040.2010.02192.x>). Includes the ability to fit the
Arrhenius and modified Arrhenius temperature response functions (see Medlyn
et al., 2002, <doi:10.1046/j.1365-3040.2002.00891.x>) for maximum rubisco
carboxylation rates (Vcmax) and maximum electron transport rates (Jmax) (see
Farquhar et al., 1980; <doi:10.1007/BF00386231>).
