// FVarLevel:
// A "face-varying channel" includes the topology for a set of face-varying
// data, relative to the topology of the Level with which it is associated.
//
// Analogous to a set of vertices and face-vertices that define the topology for
// the geometry, a channel requires a set of "values" and "face-values". The
// "values" are indices of entries in a set of face-varying data, just as vertices
// are indices into a set of vertex data. The face-values identify a value for
// each vertex of the face, and so define topology for the values that may be
// unique to each channel.
//
// In addition to the value size and the vector of face-values (which matches the
// size of the geometry's face-vertices), tags are associated with each component
// to identify deviations of the face-varying topology from the vertex topology.
// And since there may be a one-to-many mapping between vertices and face-varying
// values, that mapping is also allocated.
//
// It turns out that the mapping used is able to completely encode the set of
// face-values and is more amenable to refinement. Currently the face-values
// take up almost half the memory of this representation, so if memory does
// become a concern, we do not need to store them. The only reason we do so now
// is that the face-value interface for specifying base topology and inspecting
// subsequent levels is very familiar to that of face-vertices for clients. So
// having them available for such access is convenient.
//
// Regarding scope and access...
// Unclear at this early state, but leaning towards nesting this class within
// Level, given the intimate dependency between the two.
// Everything is being declared public for now to facilitate access until it's
// clearer how this functionality will be provided.
