Quiz 24
=======
Implement the module for memory management as shown in the video. If you find
bugs fix them ;-) Make sure that the memory managed by the module will be freed
before programs using the module terminate if they follow the convention that
before termination _finalize()_ gets called.

Use the module for the calculator:

- Remove debugging output from the region-based memory management (or only
  produce debug information if some special macro is defined).

- Constructors for types _struct Expr_ should allocate memory with
  _allocFromMemRegion()_.

- Remove the destructor _deleteExpr()_ from the module for expression nodes.

- Add a function _deleteAllExpr()_ that releases all memory allocated for
  expression nodes.

- Make sure that there are no memory leaks in the calculator. Validate this with
  _valgrind_.

- In the __lcc__ compiler the parameter corresponding to our enum constant for
  _extra capacity_ is 10K ($10 * 1024$). For the quiz leave it a 64. It makes
  it easier to write tests this way.

How to Submit
-------------

You have to submit a __tarball__ _quiz24.tgz_ of your project. In your project
directory do the following:

- Run _make clean_
- Create the tarball with

  ---- CODE (type=txt) -----------------------------------------------------------
  tar cfvz quiz24.tgz *
  --------------------------------------------------------------------------------

- On _theon_ you can submit the tarball with _submit hpc quiz24 quiz24.tgz_
