Some minor doc updates

#84

[aradhakrishnanGFDL]

@Ciheim looks good to me. It's a bit hard to review without the actual sphinx page, so we can merge this in and work on more docs as needed.

But.. did you address the following in some form? or want to table this for later?

Item 3: Using FRE-CLI section needs major updates, especially to reflect --config option
(check if verbose option is in fre-cli, open issue on this separately if not)

Using FRE-CLI (GFDL only)¶

[Ciheim]

@aradhakrishnanGFDL The --config option is explained in the flags section. Do you think there needs to be an example of a config being used for a fre-cli call? What other updates would you suggest for that section?

I've opened a new issue for the verbose option in the fre-cli catalog builder tool.

Got it. There needs to be documentation in the fre-cli land perhaps for fre build catalog etc. There seems to be a hyperlink from the catalog builder docs to fre-cli, so that's good for now. Merging in. Please make sure fre-cli docs are updated coordinating with @ceblanton
