not an issue: small suggestion for recycler.py

[greytear]

I thought it would be useful (for debugging purposes, for example) to add date and time to the recycler.py script.
Thus, i added to my local recycler.py, on line 194

print(str(datetime.now().strftime('%Y-%m-%d %H:%M:%S')) + " --> " + str(len(COMP.nodes())) + " nodes remain in component")

with the obvious

from datetime import datetime

Hope this can be useful
