/**
 * `building.validity.valid` is true if the building passes a few validity
 * tests. This is useful for testing.
 *
 * There are several reasons that it could be false:
 * 1. There's more than one room with the same name.
 * 2. There's at least one hallway that doesn't have any nodes (Forks or
 * Stairs) to connect it to the rest of the building.
 * 3. The graph isn't connected (`connectedSections > 1`). That means there's
 * a group of at least one node that isn't connected to the rest of the graph.
 * 4. There are negative edge weights in the graph.
 *
 * If `building.validity.valid` is false, `building.validity.reason` gives
 * the reason why it's invalid.
 *
 * `connectedSections` is a string[][], where each string[] is a list of nodes
 * that are all connected. (Each string[] forms a connected graph.) This is
 * useful for debugging to figure out which nodes aren't connected to the rest
 * of the graph.
