This implements a general wrapper for dense_hash_map and dense_hash_set, that falls back to unordered_map and unordered_set, if sparsehash is not enabled.

This also changes the semantics of random_rewire() when parallel edges / self loops are forbidden, but the initial graph contains them. Now, instead of throwing an exception, the rewiring is attempted, with no new parallel edges / self-loops being created. Under some circumstances, if the degree sequence is graphical, eventually the graph can become simple after sufficiently many sweeps.

This also improves some of the existing shuffling strategies with a fast alias sampling. The parameter names of the random_graph() and random_rewire() functions have been made more consistent.

Dumping boost::adjacency_list<> improves memory usage by a factor of two, and also slightly improves performance in some cases.

This enables the inclusion of the non-boost tr1 headers if a recent enough version of libstdc++ is detected. This als fixes a bug with clang when sparsehash pulls unwanted tr1 headers.

This makes the code more efficient if the input parameter combinations are much larger than the graph itself.

This implements a general "blockmodel" generation / rewiring algorithm, using Gibbs acceptence / rejection sampling (a.k.a Metropolis-Hastings). This also implements some optimizations in the rewiring code, which makes it more efficient on filtered graphs.

This introduces several simplifications and corrections to the graph rewire algorithm, to guarantee unbiased sampling. Now a move is outright rejected if it produces a self-loop/parallel-edge, instead of retried. This also adds a "non-sweep" mode, where edges are rewired randomly, possibly with repetition. The edge moves are now simplified to the target of the edges only, since swaping sources is redundant. The number of iterations can now be explicitly modified, so it is not necessary to call the function more than once, and it is emphasized in the documentation that only after sufficiently many iterations can the graph be guaranteed to be fully mixed.

This enables support for older versions of GCC (>=4.2), by falling back to the boost tr1 implementation when the GCC version is less than 4.4.

This includes also some internal refactoring, and bug fixes.

This extensively modifies the random_rewire() algorithm, so that only either the source or the edge of each edge is rewired (not both, as previously), and no parallel edges are created during the algorithm (if desired). The new version is much faster, and never gets stuck. However, more than one run may be necessary in order to obtain a uniform shuffling.

This fixes a problem, where the underlying edge directionality would cause correlations to arise when rewiring undirected graphs. Now each edge is correctly considered in both possible orientations, which are chosen randomly.
