Speed up NetworkTMLE

[pzivich]

Right now the bottleneck is the creation of the data for the IPW numerator / Monte Carlo integration. This should be easy to speed up (via Pool) or using some clever tricks in generation. The real issue is the creation of all the summary measures for each copy (lots of matrix multiplications)

[pzivich]

So, the packing in Pool is expensive. However, when calculating all the different summary measures, this initial expense becomes worthwhile. I would like to find something that is quicker than Pool with the packing into a list. If I can find something that is, then everything will be far faster

namespace looks like a promising alternative to access all the objects without copying
