This adds a command in Custom Entity that acts on the input signal.
Acting on this input signal before setting it should raise an exception
from dynamic-graph.

test_dg_exc was added to check that, and fails for now.

While here, fix exception type check in test_bindings.

As, from the docs:
> Passing arguments of the wrong type (e.g. passing a list when an int
> is expected) should result in a TypeError.

Thanks @jmirabel

thanks @jviereck

While here, develop test from previous commit, and fix another test in
the same file.

fix #36

For now, this test doesn't pass, as an exception is not properly fired,
but we get a segfault instead.

can have time to write on the output stream.

The logger is implemented with a map using __FILE__ and __LINE__.
Using the defaut values means that the same counter is used for
all the streams. This is jeopardizing the test.

Is anyone who tried the tests before ?

Former version crashed in case of syntax error
(cf test_syntax_error.py)

This unit test shows that after a given number of run
of the same file, the error changes.
Unfortunately, this can not be automatically verified, since
the result is printed in the python error stream, and cannot be
redirected.
