implemented derivation of gradient weights via rotation

See merge request pycodegen/pystencils!15

Markus Holzer authored 5 years ago and Markus Holzer committed 5 years ago

derive gradient weights of other direction with
already calculated weights of one direction
via rotation and apply them to a field.

as_matrix gives now a deprecated warning and as_array is no newly implemented to replace it. as_array works with MutableDenseNDimArray now instead of Matrix

`instruction_set`

Declare FieldShapeSymbol and FieldStrideSymbol as strictly positive

Fix #10: Avoid jinja2 dependency

Closes #10

See merge request !18

This commit avoid dependency of core pystencils on jinja2.
However this could make the printing of some AST-nodes less elegant.

- rename header Field.h is not a unique name in waLBerla context
- add PyStencilsField.h
- bindings were lacking data type

functions like absolute values could not be used in CUDA backend since
known_functions was replaced instead of updated

Add CudaBackend, CudaSympyPrinter to extract CUDA-specific code from CBackend, CustomSympyPrinter
Cuda built-ins are added to CudaSympyPrinter.known_functions to use them as sympy.Function
