Add an Expand parameter to turn off the subclass reasoning function?

[chunyuma]

It seems like the ARAX_expander module automatically does the subclass reasoning for a query.

Example:

add_qnode(ids=DRUGBANK:DB01050, key=n00)
add_qnode(key=n01)
add_qnode(ids=MONDO:0008383, key=n02)
add_qedge(subject=n00, object=n01, key=e00)
add_qedge(subject=n01, object=n02, key=e01)
expand(kp=infores:rtx-kg2)
resultify()
filter_results(action=limit_number_of_results, max_results=5)

One of the results I got is:

 'description': 'No description available',
 'edge_bindings': {'e00': [{'attributes': None,

The ARAX_expander generates some subclass curies for the original qnode MONDO:0008383. I'm wondering if we can add a parameter to turn off this automatic subclass reasoning function when we don't need it.

This is not an urgent request but I think it will be useful for some situations.
