Graph created from a Design is empty

Changing the imports on tisane/graph.py has helped, like so:

from tisane.og_variable import (
    # AbstractVariable,
    Nominal,
    Ordinal,
    Numeric,
    # Unit,
    Treatment,
    # Nest,
    RepeatedMeasure,
    # Has,
    # Associate,
    # Cause,
    # Moderate,
    GreaterThanOne,
)
from tisane.variable import (
    Measure,
    Unit,
    AbstractVariable,
    Has,
    Associates,
    Causes,
    Moderates,
    Nests
)

I'm just not sure if I'm breaking anything by doing so.

ts.og_variable was a temporary hack I had used to test a few tests for API changes.

Since commit, this is no longer a bug. The graph has all the expected variables and edges. This means that this program:

        student = ts.Unit("Student")
        # Variables instantiated through Units
        race = student.nominal("Race", cardinality=5)
        ses = student.numeric("SES")
        test_score = student.numeric("Test score")
        tutoring = student.nominal("treatment", cardinality=3)

has the following nodes/passes the below tests that were failing before:

        self.assertTrue(gr.has_variable(student))
        self.assertTrue(gr.has_variable(race))
        self.assertTrue(gr.has_variable(ses))
        self.assertTrue(gr.has_variable(test_score))
        self.assertFalse(gr.has_variable(tutoring))

See test_graph.py for the above test case.
