Adopted contributions by Christian.
* Contributions by Christian, resulting in vast speed and memory improvements
for large factor graphs:
- Sparse implementation of nodes->edge conversion table _E12ind in bipgraph.h
- New FactorGraph constructor that constructs from given ranges of factors
and variables
- Optimization of FactorGraph constructors
* FactorGraph constructors no longer check for short loops and for
negative entries. Also, the normtype is now Prob::NORMPROB by default.
* Moved everything into namespace "dai"
