How do I load a Slice object in Research 

Tried 

%matplotlib inline
# Imports

# added this in addition to all other imports

from   QuantConnect.Lean.Engine.DataFeeds import TimeSlice


# Create an instance. this works fine
qb = QuantBook()
spy = qb.AddEquity("SPY")

slice = TimeSlice()
print hasattr(slice,"QuoteBars")

Can anybody help?

Also is there a way to create an empty Research page without all the default data at startup.? Erasing all that stuff takes time and if I leave it it distracts others looking at the code.

Thanks
