Network K Functionality

[jGaboardi]

Superseded by #477. See specifically this comment

The formulation of the Network K in spaghetti does not appear to be from any of {1,2,3,4}, thus it should probably be created from scratch using {1}. With this both local and global, and auto and cross methods can be implemented.

The formulation of the Network K in spaghetti is from {3}. We will considering more recent formulations of the Network K in the future, specifically check {1, 6}. With {1} both local and global, and auto and cross methods can be implemented
