Commit before merging in Python branch: * converted more examples: poincare, rips, some fitness * two generators for Rips complexes * ChainWrapper uses stl algorithms for everything, added CountingBackInserter and switched SizeStorage to use operators * retabbing files along the way * added #957a (namespace dionysus)

Write an audit for the data structure.

-DBOOST_UBLAS_TYPE_CHECK=0 is necessary since otherwise Boost's uBLAS gives a compile-time error 
when it doesn't find sqrt for polynomials. It doesn't actually need it (e.g., for LU-decomposition, 
but it looks for it during type check). (File a bug report with Boost?)
