All thermophysicalFunctions, NSRDS, API and the fast uniform and non-uniform
tables have now been converted into the corresponding Function1<scalar> and
Function2<scalar> so that they can be used in other contexts, e.g. diffusion
coefficients for multi-component diffusion and in conjunction with other
Function1 and Function2s. This also enables 'coded' Function1 and Function2 to
be used for thermo-physical properties.
Now all run-time selectable functions are within a single general framework
improving usability and simplifying maintenance.
