Globals Import Change needed in circle.py (py3 branch)

[weloewe]

In the using the py3 branch, encountering two changes needed to run fprof:

diff --git a/pcircle/circle.py b/pcircle/circle.py
-from globals import T, G
+from pcircle.globals import T, G

diff --git a/pcircle/utils.py b/pcircle/utils.py
-from globals import G
+from pcircle.globals import G

Please let me know if this is needed or if a different approach is successful in running the fprof without these changes.
