Allow the model to be called with variable inputs

[benmsanderson]

Allow capacity for model to be run without input text files. Either with concentrations/emissions/forcing files defined as pandas dataframes or simple arrays.

Ok, just jotting down some thoughts on how I would want this to work, so I want the user to be able to either send a file path option or just a Dataframe or array for the following (for the various run types for which they are needed):

• emissions file
• concentrations file
• gases file
• forcing file
• perturbations files For the following I want to allow the user to optionally give a file path, a DataFrame/array, or just run with defaults:
• natural emissions for n2o
• natural emissions for ch4
• solar emissions
• volcanic emissions

For each of these I want the user to be able to mix and match between using files and sending data more directly... I might end up building some input checking infrastructure for this...
