C++ Tutorial "Hello World" has incorrect install instructions

[abachma2]

in the C++ Hello World tutorial it tells you to clone cyclus/cycstub but the cycstub github page has different instructions and says that the method described on the tutorial page is "Depreciated".

@dean-krueger identified this as a needed update to the website. The Cycstub repo says that upon the next release (i.e., 1.6 at this point) it will be removed from Github. We should then think about this one. I haven't done much c++ archetype development, but this did seem like a handy way to help new developer. Having said that, it probably needs some updates should we decide to keep this.

I welcome discussion on this one.

This repo is replaced by a CLI that lives in cyclus that accomplishes the same thing. Anyone with cyclus installed can run

$ cycstub --type facility mypath:mylib:MyFacility

and get the same thing. A documentation change should take care of it.

That's super useful! I'll give it a try later to make sure it still works well and then try to update the documentation for this.

[abachma2]

OK. So quickly playing around with it, it does work (I think). It created a new cyclus input file to run the archetype with a NullRegion and NullInst (did --type facility). Not quite sure if it creates the archetype files that you're then supposed to modify to build your archetype.

I think this was resolved in #419
