Pypi testing

Aims to resolve #182.

Quite basic hotfix for pip not being able to access harmonic submodules.

• added .vscode/ to .gitignore.
• added license info to setup.py setup container
• changed packages to simply 'harmonic' in setup.py setup container. This change was inspired by looking at similar repos' setup.py configurations.

Tests this change fixes things:

v1.0.0:

python>>> import harmonic as hm
>>> test = hm.Chains(2)
Consolde ouput: ImportError module harmonic has no attribute 'Chains'

python>>> dir(harmonic)
Consolde ouput:['__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__']

After this PR:

>>> import harmonic as hm
>>> test=hm.Chains(2)
>>> print(test)
<harmonic.chains.Chains object at 0x7ff0c6b1ce20>

>>> dir(hm)
['Chains', 'Evidence', 'Shifting', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__', 'chains', 'evidence', 'logs', 'model', 'utils']

The tests I am doing to see if it works is as follows:

From root dir in fresh conda py3.8.0 env:

(harmonic) $  pip install -r requirements/requirements-core.txt && pip install . (1)

Then moving to another random dir in my home folder and running a python interpretor:

(harmonic) >>> import harmonic as hm
(harmonic) >>> test = hm.Chains(2)
(harmonic) >>> print(test)

This seems to work now!

This branch also works the other src way with new fresh conda env this running getting_started.sh then pytest etc

Looks good! :)
