Add ptasks in the Python bindings
- This adds several functions in the Python bindings used for manipulating
ptasks, such as
parallel_execute
orexec_init
. - This also adds the
Engine.set_config
function, needed for changing the configuration to'host/model:ptask_L07'
in the script. - Finally, an
exec-ptask.py
example is added, exact translation of the C++ examples4u-exec-ptask.cpp
.
