utilities import in synaptics.py

[chadestep]

I keep getting an import issue specifically from this module when importing neurphys. The notebook spits out an error that it "can't find utilities," even though two other modules import the utilities module the exact same way.

I temporarily got around this by commenting out the synaptics import in the init.py until we find a fix.

Fixed the import statement and edited the init file
