Workspace Method abs_coefCalc

Description

Calculate absorption coefficients.

This function calculates both the total absorption (abs_coef), and
the absorption per species (abs_coef_per_species).

The method calls four other  methods:

1. abs_xsec_per_speciesInit:
   Initialize abs_xsec_per_species

2. abs_xsec_per_speciesAddLines:
   Calculate cross sections per tag group for line spectra.

3. abs_xsec_per_speciesAddConts:
   Calculate cross sections per tag group for continua.

4. abs_coefCalcFromXsec:
   Calculate absorption coefficients from the cross sections by
   multiplying each cross section by n*VMR.

This is done once for each tag group (output abs_coef_per_species),
and for the sum of all tag groups (output abs_coef).
