"""
This is the main function of this file. It takes as input an MCM file, and from it generates
5 files for use by AtChem2's Fortran code:
- 'Generic Rate Coefficients' and 'Complex reactions' go to gen_dir/mechanism.f90 with little more than formatting
changes - each line is replicated in full but with each named rate converted to an element in the vector q.
- The rates defined in 'Reaction definitions' also go to gen_dir/mechanism.f90 as elements of the vector p.
- The species involved as reactants (respectively products) in reactions in 'Reaction definitions' are split up into individual
species, and their species and reactions numbers go to mechanism.reac (respectively mechanism.prod). Combining
mechanism.reac, mechanism.prod and the last section of gen_dir/mechanism.f90 gives the original information
contained in 'Reaction definitions' but in the format that AtChem2 can parse.
- The numbers and names of all species encountered go to mechanism.species.
- The numbers and names of all RO2 species in 'Peroxy radicals' end up in mechanism.ro2.
:param input_file: string containing a relative or absolute reference to the mcm file to be processed.
:param gen_dir: string containing a relative or absolute reference to the directory in which the function should
place mechanism.f90. This is normally model/configuration.
:param mech_dir: string containing a relative or absolute reference to the directory in which the function should
place mechanism.{prod,reac,ro2,species}. This is normally model/configuration/ for the given model.
