New diagnostics always writes some fluxes even in linear simulations

[David Dickinson]

In a linear simulation we get es_flux_vs_e (apar_flux_vs_e) etc. in the output file even if we don’t want to write fluxes as calculate_fluxes contains create_and_write calls for these variables. We call calculate_fluxes in several conditions including cases where we don’t want to save the fluxes to file.

@Peter Hill any thoughts on this given you’ve just been dealing with diagnostics?

[Peter Hill]

This should be fixable now, as we only need to call the routines in the cases where we intend to write the fluxes – I’ll take a look

Default write_flux_line to off in new diagnostic module

Automatic close was premature.
