* NEW: Any operators of the _operator interface can be optional now. But
consequently, division by zero must be raised by the implementation.
* NEW: Implement Vector arithmetic operators.
* NEW: Rename some Matrix methods.
* NEW: Implement Polynomial arithmetic addition and substraction.
* BUG: Fix Polynomial to string conversion.
* NEW: Complex.Handle is a new property that returns the memory address of
the underlying complex number in memory.

* NEW: '_operators' interface has been renamed as '_operator'.
* NEW: Arithmetic operators now can be applied on two objects with
different classes. One at least must implement the '_operator' interface.
* NEW: Each class that implements the '_operator' interface has now an
automatic priority that follows the load order. When a binary operator
has two objects that implement two different '_operator' interface, the
one having the highest priority is used.
* NEW: Implementing all methods in the '_operators' interface is not
mandatory anymore. If one method is not implemented, then it is replaced
by a function that raises a 'Type mismatch' error.

* NEW: Matrix arithmetic has been implemented.
* NEW: Matrix.Determinant() method.
* NEW: Matrix.Invert() method.
* NEW: Matrix.Transpose() method.
* NEW: Matrix _call special method multiplies a matrix by a vector.
* NEW: Vector <-> Array conversion.

* OPT: Remove a useless test in the macro that returns the class of an
object.
* OPT: Some little optimization in some type checks.
git-svn-id: svn://localhost/gambas/trunk@4939 867c0c6c-44f3-4631-809d-bfa615b0a4ec
* NEW: Put every '_operators' interface related methods in the same source
file.
[GB.GSL]
* NEW: Polynomial _call() special method now is a synonymous of its Eval()
method. That way, you can write 'P(X)' to get the value of P(X).
