class constructor, so a caller can pass in an expression compiler.
Every expression occurring in the syntax is compiled first (even the
macro name in use-macro; but not slot names, nor the macro name in
define-macro).  If the expressionCompiler argument is left
unspecified, a default compiler is chosen whose compiled output is
identical to its input.

  value.  This affects TALCompiler.py and TALInterpreter.py, and
  affects the output of the non-local-macro expansion tests.  The
  TALVisitor.py module is *not* yet fixed to do this.

- In order to do this, I had to change the "program code" format for
  the attribute list: the 3rd item of an attribute description tuple,
  if present, now names an action, and the remaining tuple items are
  arguments for that action.  Two actions are recognized: "replace"
  replaces the attribute with the outcome of evaluating the expression
  given by the next tuple  item; "macroHack" replaces the attribute
  name with "use-macro" and its value with the current macro, but
  only if we're inside macro expansion and the attribute name ends in
  ":define-macro".

- The test suite is now error-free for "./runtest.py -c" but shows some
  errors for "./runtest.py".

- Added a primitive debugging flag to the TALInterpreter class.

- Update the README.

- Should I check for spurious TAL attributes even when doing just
  METAL (macro) expansion?

- Should I turn all the other errors into exceptions too?  (Currently
  they are all print statements.)
