Detailed Description

Multimodal networks.

Represents a multimodal network. A mutimodal network is represented by composing TModeNets (disjoint sets of nodes) and TCrossNets (disjoint sets of edges that connect nodes in two TModeNets). TMMNet contains methods to create TModeNets and TCrossNets by name, and returns pointers to them. All operations more granular than this, like adding nodes and edges, are run directly using methods provided in the ModeNets and CrossNets.
