1. Output different-colored edges for parent-child resource
relationships
2. Allow the changing of edge colors via command-line parameters
3. Allow the skipping of the parent-child graph or the
dependency graph when calculating all edges
This modifies the Graph interface slightly to allow an edge to specify
what color should be used when drawing it.

// Package graph defines LumiGL graphs. Each graph is directed and acyclic, and the nodes have been topologically
|
|
// sorted based on dependencies (edges) between them. Each node in the graph has a type and a set of properties.
|
|
//
|
|
// There are two forms of graph: complete and incomplete. A complete graph is one in which all nodes and their property
|
|
// values are known. An incomplete graph is one where two uncertainties may arise: (1) an edge might be "conditional",
|
|
// indicating that its presence or absence is dependent on a piece of information not yet available (like an output
|
|
// property from a resource), and/or (2) a property may either be similarly conditional or computed as an output value.
|
|
//
|
|
// In general, LumiPacks may be evaluated to produce graphs. These may then be compared to other graphs to produce
|
|
// and/or carry out deployment plans. This package therefore also exposes operations necessary for diffing graphs.
