volumetric modelling with function representations

• compas_vol is an extension package built on top of compas core.
• To get started, I recommend you create a separate environment in an Anaconda Python 3.7 installation. The details are described here: https://compas-dev.github.io/main/gettingstarted/installation.html
• With the newly created environment active, make sure you have git installed. If not, in the terminal (Mac) or Anaconda Prompt (Win) run conda install git.
• Then install compas_vol directly from source, running pip install git+https://github.com/dbt-ethz/compas_vol
• The example notebooks use ipyvolume for isosurfacing and mesh display. Install it with conda install -c conda-forge ipyvolume
