Major ones:
* Be consistent: "numeric type" and "arithmetic operator".
* if/swtch take "simple statement" not "short variable declaration".
* There was a comment that implied for x,y := range z() might
  evaluate z() multiple times.  I deleted it.

move array down next to slice.

fix type equal example for structs.

- require ()'s around composite literals at the if/for/switch control clause level
- fixed a nasty bug: passing a value instead of a pointer to a value to an interface
  variable - and not noticing that the value is copied

(i.e., the status quo with braces in composite literals).

- removed unneeded code that accumulated over time
- change src from string to []byte (perhaps should be io.Read
but that has some other disadvantages)

- converted more of AST and parser to use interfaces and explicit
structs for individual Go constructs (can be replaced now with
interface calls such that the parser becomes AST structure
independent, as suggested by rsc)
- added more tests (find all .go files under GOROOT)
- (temporarily) lost html links for identifiers when generating
html output
- TODO: lots of cleanups

Moved assignment compatibility to its own small section. Although most rules are type-specific,
some are not and it reduces redundancy to combine them.
Also, more experimentally, wrote a section on comparison compatibility.
