- different approach in pystencils: absolute indexing

- extended pystencils
- Visualization for list LBM
- not yet working

- updates in lbmpy benchmark
-> enables better numa placement

- update kida vortex benchmark

- support aligned load/stores
- nontemporal stores
- aligned memory allocation for arrays and temporary buffers

- vectorization for loops with ranges that are not a multiple of vector width
- vectorization for variable sized loops if special transformation
  replace_inner_stride_with_one is run

- move_constants_before_loop: in the rare case that a symbol
  with same name exists in move target - the assignment is not moved
  previously an exception was raised in this case
- consistent naming of intermediate base pointers

- works also with ps.kernel decorator

- previously moved only SympyAssignments
- relevant for custom boundary nodes, which are now pulled before loops

- SSA form is checked
- loop independence condition is checked
- bug fix in Field.create_generic when using index_shape

- uses ast instead of text-based editing
- can handle Piecewise defined functions
- new decorator for simplified usage

- when running multiple pystencils instances, sometimes errors happened
  because one process might have partially written a cached file, which
  is already read before writing was finished
-> switched to "atomic write" (only on linux yet) that uses os.rename
   which is guaranteed to be atomic

- flags can be force when setting boundaries, this is helpful for:
- setting up quantities (e.g. relaxation rate..) dependent on current
  flag configuration
- bit operation fix when pickling: function has to have the same name
  as the python object
