TrigPSC: Define printfunc before including JO files.

For compatibility between py2 and py3, athena JO files use `printfunc()' instead of either the py2 print statement of the py3 builtin print() function. (The reason for not just using print() along with from future import print_function is that with an included file, the print_function future can't be limited to one file.)

Define printfunc here to be compatibile with what's done in athena.
