Eddie Hebert ca9fdcfe84 Uses a Portfolio object instead of an ndict.
Gains some performance by using a 'regular' object instead of
an ndict.

Also, directly sets up the values that we return, instead of going in
between with __core_dict and then removing values.

In it's entirety performanc.as_portfolio is the current
highest bottleneck, working on reducing time spent in that function.
