v1.11.2

v1.11.2:
Except numpy and scipy, most other third-party packages are imported lazily to reduce the number of required packages for basic use. Several pip installs are available:

1. pip install luxpy
2. pip install luxpy[matplotlib]
3. pip install luxpy[light]
4. pip install luxpy[heavy]

The first one only auto-installs numpy and scipy, the next one adds matplotlib for plotting, ... (see setup.py for details on the other options). Many of the additional packages will be installed automatically (if not already) on first requirement.
