Update CLIs to use "review" base command

[WilliamsTravis]

Why this feature is necessary:
This syntax will make it easier to find available review CLI commands. For our reVX CLI, we have a lot of commands that are not intuitively associated with reVX (e.g., setbacks) while for the reV model we have a reV base command to give the user a nice place to start. I find the latter much more intuitive and easy to work with.

A possible solution is:
Use a generic review CLI with command options. So, you would type review and then the help file would list the available commands. The option would then run the target command, so, something like this:

review make-maps -i input.csv -t wind -o wind_maps/ -d 300

We already have a reView command that launches the development server for the DASH gui. This would have to become something like review gui.

How about reView app for the DASH gui?
