''' Create a profile region around a list of statements. For
example:
>>> from psyclone.parse.algorithm import parse
>>> from psyclone.parse.utils import ParseError
>>> from psyclone.psyGen import PSyFactory, GenerationError
>>> from psyclone.psyir.transformations import ProfileTrans
>>> api = "gocean1.0"
>>> filename = "nemolite2d_alg.f90"
>>> ast, invokeInfo = parse(filename, api=api, invoke_name="invoke")
>>> psy = PSyFactory(api).create(invokeInfo)
>>>
>>> p_trans = ProfileTrans()
>>>
>>> schedule = psy.invokes.get('invoke_0').schedule
>>> print(schedule.view())
>>>
>>> # Enclose all children within a single profile region
>>> p_trans.apply(schedule.children)
>>> print(schedule.view())
This implementation relies completely on the base class PSyDataTrans
for the actual work, it only adjusts the name etc, and the list
of valid nodes.

# Unlike other transformations we can be fairly relaxed about the nodes
# that a region can contain as we don't have to understand them.
