// vertex (v)
// 
// Vertex class. Not to be confused with LDVertex, which is a vertex used in an
// LDraw code file.
//
// Methods:
// - midpoint (vertex&): returns a midpoint
// =============================================================================

// bearing
// 
// A bearing is a combination of an angle and a pitch. Essentially a 3D angle.
// The project method projects a vertex from a given vertex by a given length.
// 
// Prefix: g, since b is bool
