c2a772e797 Compile selection expression 
When running a selection, compiling the expression into a code object
so that it does not need to be re-parsed per every iteration.

Since it saves one parse per iteration, the gains become more
noticeable as the size of the relations grow.

a8c1b2a463 Revert copy on write optimization 
In case of multiple renames, all of the resulting relations will point
to the same data, so writing on one and marking its only known copy
as writable would be incorrect.

For this to work, all the references should be kown to all the other
instances.

It is probably not worth to implement it.

Implemented test for the update

5073567757 Change how python tests are executed 
Require them to have assert rather than testing the
result variables set.

This makes for way simpler code.

Now also prints stacktrace to know where the problem occurred.

521ffd5d41 Reduce amount of useless copies 
In case of a rename, the original relation and the resulting relations
are pointing to the same set.

In case of functions that change the relation, such as insert, a copy is
created to be able to write on it. But when writing on the other relation
a new copy would have been made too.

This fixes it, now when changing one relation, the other is marked as
writable as well.

e24e757342 Moved most of install logic to makefile

d597076038 Subtle bug that occurred selecting after a join 
Outer joins add the placeholder '---' that is used as some sort of NULL
value.

However select operations on such relations would always fail, because
relations are supposed to only contain values of class rstring, and
the placeholder was added as a regular string.

As a consequence, automatic casting would always fail, and the select
would always raise an exception.

Added a new test case with this specific case in mind.
