This commit adds an optional namelist to ModEM. The namelist should be a file in the current working directory with the name of: `namelist.modem.nl`. The namelist is only read if the `namelist.modem.nl` file is found in the CWD otherwise no attempt is made to read it. The goal for the namelist is to provide an extra location to provide ModEM options that neither fit into the forward control file, or the inversion control file. So far the namelist only really has one option that alters the execution of ModEM, verbose setting. If set in the namelist, the verbose setting will override the default verbose setting or the verbose level passed in through the command line. There are three other options that can be set in the namelist. These are all under the '&grid' section. These options are: SFF, primary_field, and primary_field_file. At the moment, these options do nothing except set corresponding variables in userCtrl file. These variables are added here to assist Anna with her spherical/secondary field formulation work. The two sections are both optional in the namelist. They can either be completely omitted or written in any order in the namelist file. This provides some great flexibility for the user. It also should be pretty easy for other developers to see how to add a new section. An example namelist can be generated by using a hidden command line option: `./Mod3DMT -N`. That routine wont create the file if there is a namelist already present. As we use the namelist more, we can consider adding in a help message about `-N`.

This merge adds an optional namelist to ModEM. The namelist should be a file in the current working directory with the name of:
namelist.modem.nl.The namelist is only read if the
namelist.modem.nlfile is found in the CWD otherwise no attempt is made to read it.The goal for the namelist is to provide an extra location to provide ModEM options that neither fit into the forward control file, or the inversion control file.
So far, the namelist only has one option that alters the execution of ModEM: the
output_levelsetting (normally set by -V on the CL). Ifoutput_levelis set in the namelist, the verbose setting will override the default verbose setting or the verbose level passed in through the command line.There are three other options that can be set in the namelist. These are all under the '&grid' section. These options are:
SFF,primary_field, andprimary_field_file. At the moment, these options do nothing except set corresponding variables inuserCtrldata structure. These variables are added here to assist Anna with some of her on-going spherical/secondary field formulation work.The two namelist sections (
&settingsand&grid) are both optional. They can either be completely omitted or written in any order in the file. This provides some great flexibility for the user. It also should be pretty easy for other developers to see how to add a new section.An example namelist can be generated by using a hidden command line option:
./Mod3DMT -N. That routine wont create the file if there is a namelist already present. As we use the namelist more, we can consider adding in a help message about-N.
