This is a major overhaul of the code and docs in order to enable new macros. I'm seeking constructive feedback here please, such as what could help you understand this, or what new kinds of test macros you would like, and the like. Rust macros are turning out to be my favorite Rust feature-- the code flexibility across multiple types makes for good dynamic-like capabilities.
