Multyscale spatial filtering models of brightness/lightness perception

Installing

Multyscale is not yet available on package registries (e.g., PyPI). Instead:

clone from GitHub (TUB):

git clone git@github.com:computational-psychology/multyscale.git

Multyscale can then be installed using pip. From top-level directory (which contains setup.py) run:
```
pip install .
```
to install to your local python library.

For developers, use:
```
pip install -e .
```
for an editable install; package now does not need to be reinstalled to make changes usable.
