Fixed a bug in field.py

- test run again
- notebooks not yet

- assignment collection
- sympyextensions

- added documentation
- PEP8 renaming

- Previously sympy.Eq was used to represent assignments. However Eq
  represents equality not assignment. This means that sometimes sympy
  "simplified" an equation like a = a  to True,
-> replaced sp.Eq by pystencils.Assignment everywhere
- renamed EquationCollection to AssignmentCollection

- switched to google style docstrings
- removed dead code
- started to annotate types

for fields without index dimensions the indices (0,) and () have been
treated equivalently, but did not compare equal

- notebooks are considered in coverage analysis now
   -> custom notebook runner plugin adapted
- added images for documentation

- shortened the longest running tests, moved some configurations
  to longrun

Modified the gitlab-ci for benchmarking purposes
Created a new Dockerfile for benchmarking purposes, which includes the
intel compiler.
Docker file now has likwid installed as well.
Created a machine file for the benchmarking machine.
Kerncraft updated and fixed.

TODOs:
    - cleanup of the yaml files
    - Test the Skylake machine file and kerncraft_coupling for correct
      behaviour

-> one place to switch between cpu and gpu

label -> target
ceIdx -> superscript

- merged finite difference functions into one function
- put derivative operators from lbmpy into pystencils

- in-kernel Neumann boundaries
- flag-interface for boundary handling makes one flag field multiple
  boundary handlings possible
- generator: support for bitwise logical operators
