Update documentation

[Raul-Barajas]

Some changes have been made in the way functions are defined; for example, OptiNode() does not work as in the first versions. Could you please update the documentation.

Hi @Raul-Barajas, apologies for the delay in responding. Is there an instance in the documentation that you are hoping would be updated? Or are you thinking the docs could highlight more clearly what is not supported in the new version? I do not think we list in the docs all the changes under the new version, but it is possible we could make more clear that some functions have been removed.

You are correct that OptiNode() is not longer supported in v0.6+. I think optinodes can be added now only via the @optinode macro or the function add_node. I do not think we have any instances of using OptiNode() in any of the current documentation examples, but please let us know if one was missed.

@jalving I also noticed that the docs include PlasmoPlots calls, though PlasmoPlots is restricted to older versions of Plasmo. I think this could be good to update as well. I can try to take a look at updating PlasmoPlots in the next couple weeks to make a version that's compatible with Plasmo v0.6+. I am assuming this will require releasing a new version of PlasmoPlots.
