Changed Simplex::IsNegative to Simplex::isNegative, will slowly make all of the variable names conform to one standard.
Removed some prints from dec.hpp that created a dependency on iostream.
Made index inherit from std::array<unsigned int,N> to take advantage of iterators and such.
Added functionality for simplicialComplex to output all of hte simplices closely packed and such that the indices are all positively oriented.
Added some lines to the compile test to make sure that the above addition to simplicialComplex worked.
