add options for screen output

[andywood]

Noah-owp will be used in several modes -- e.g., embedded in the nextgen framework, for which minimal output is desired, or in standalone mode by developers, who would typically want to see some runtime output.

We can create options for this in 2 main ways -- one to add a command line argument such as '-v[erbose] [Level]', and another is to make it an option in the namelist. Either can be backward compatible, so that if they're not specified the default behavior is minimal output.

@andywood Do you have any specific screen output options and/or printouts you'd like to see? These could be useful as we move towards using the gridded version of NOM.
