@bewagner1 The curl operator seems wrong, and will be a point of contention for many. I suggest removing it (also it doesn't have a test) to speed up the approval.

Yea I was wondering how it is mimetic operator. Doesn't seem to fit in with the rest

Hi @bewagner1 , thank you so much for your contribution!

Now that we have a few more examples, I would like them to be organized in a directory structure that reflects the same organization and categories we have chosen for our documentation. See the examples/ directory in our docs. Please update the structure of the mole/julia/MOLE.jl/examples/ directory accordingly.
Please, also use the same directory structure in the mole/julia/MOLE.jl/docs/src/ directory (where we currently do not have an examples/ subdirectory - you would need to create one)

[bewagner1]

I think that the docs in theory are good but for a reason I cannot figure out, whenever I click through the links for the examples, I encounter pages that are not .html files, so you have to click on index.html to actually render the page. Any advice would be appreciated
