I really like the idea of architecture.md -> **/architecture.md.

We overall do not have javadoc in a lot of areas, and could maybe start
working on it as we go and think about asking for it in reviews.
We are also missing the Parser Programmer’s Guide, how to add a parser to
the metron system/install etc and other things.

I feel like the code itself is pretty well documented. I updated existing
javadocs and added javadocs to classes that didn't have them before this
PR. In my opinion the level of documentation for these classes has
increased significantly.
