Changing config in mid run

[hughesadam87]

While a permanent config state changer may require some work, probably a hidden file with defaults and a state file that is set by user, it would be nice to at least to be able to change display printout. For example, to print "area" as a column on output.

Should make a _CONFIG file that is actually used and reads from CONFIG and interacts with user. When someone changes the configuration in code and wants it to be permanent, it would overwrite one of these.

I guess the primary default config should be stored in _CONFIG actually or something like .config
