Title: Add more indirector documentation.

This adds:
* general text about the indirector
* the indirected class for each indirection
* indirection-specific docs for a few indirections that I could manage to puzzle out

Please call me out if the text here is incorrect, misleading, or misled. However, it is intended to be minimal, rather than comprehensive.
