Pycomex

------------------

Introduced the new **functional API**. This is a completely new way to use the pycomex framework which
will slowly replace the old way. In this new method the whole thing is implemented with decorators instead
of context managers, which makes the entire implementation approximately 100x easier and less riddled with
side effects and bugs.

- Already changed the README example to use the functional API
- Slowly started replacing the examples with the functional API

------------------

* Fixed a bug where the inspect module would not be working correctly in executions of SubExperiment
* Fixed the version dependency for "click"
* Fixed the version dependency for "numpy"

------------------

* Added the feature of "parameter hooks". Now it is possible to register a hook with the name of a parameter
in a sub experiment to modify that parameter before the start of the experiment...

------------------

* Fixed the problem that when an exception occurs within the RecordCode context manager that this is not
properly printed. Now the entire traceback for every error is printed to the logger stream
* Moved the entire analysis RecordCode functionality from Experiment to AbstractExperiment so that it
can also be used in SubExperiment
* Fixed the bug that the analysis.py file within the archive folder would not work at all for
SubExperiment runs
* SubExperiments can now also define analysis context and those will be additive, meaning that the code
from those will be added to he end of all the analysis code that was previously created by the parent
experiment

------------------

* Updated Readme file

------------------

* Added ``Experiment.p`` as a shorthand for ``Experiment.parameters`` because that got really annoying to
write so often.
* Fixed a serious bug, where the ``snapshot.py`` file in the archive folder of an experiment was not in
fact the sub experiment but the lowest level base experiment!
