- start tracing numpy.rint and manage dtypes
- update BaseTracer to accept iterables as inputs, because NPTracer does
not get list givent the way numpy sends arguments to the functions
- this allows to make sure each node has a proper implementation
- move op_args and op_kwargs in ArbitraryFunction only
- update BaseTracer accordingly
- this input index will be useful for MLIR/lower level conversions
- it represents the input index of an Input node when considering the
traced function signature
- update code preparing function parameters to keep signature order
tests: add the possibility to test more binary operations
avoid copy-paste for binary ops, with just an option if the operation is commutative or not
refs #41, #42
- add BaseTracer which will hold most of the boilerplate code
- add hnumpy with a bare NPTracer and tracing function
- update IR to be compatible with tracing helpers
- update test helper to properly check that graphs are equivalent
- add test tracing a simple addition
- rename common/data_types/helpers.py to .../dtypes_helpers.py to avoid
having too many files with the same name
- ignore missing type stubs in the default mypy command
- add a comfort Makefile target to get errors about missing mypy stubs
