  1. Implemented support for networks with self-loops: 

    * *Network structs now have an additional element, Rboolean loops_flag.
* *NetworkInitialize() functions now takes an additional argument, Rboolean loops_flag.
* Redgelist2*Network() functions now set this flag as well.
* Macro-based backwards compatibility for calling without a loops_flag has been provided.
* GetRandDyad() returns self-loop dyads if nwp->loops_flag is TRUE.
* *EXEC_THROUGH_EDGES*() macros now skip the self-edge for the in-edge half of the iteration.
