Generates the connection graph (after all item connectivity has been updated)
In the first phase, the algorithm iterates over all items, and then over all items that are connected (graphically) to each item, placing them into CONNECTION_SUBGRAPHs. Items that can potentially drive connectivity (i.e. labels, pins, etc.) are added to the m_drivers vector of the subgraph.
In the second phase, each subgraph is resolved. To resolve a subgraph, the driver is first selected by CONNECTION_SUBGRAPH::ResolveDrivers(), and then the connection for the chosen driver is propagated to all the other items in the subgraph.
TODO(JE): Net codes are non-deterministic. Fortunately, they are also not really used for anything. We should consider removing them entirely and just using net names everywhere.

We could check that labels attached to bus subgraphs follow the proper format (i.e. actually define a bus).
This check doesn't need to be here right now because labels won't actually be connected to bus wires if they aren't in the right format due to their TestDanglingEnds() implementation.

Updates the graphical connectivity between items (i.e.
where they touch) The items passed in must be on the same sheet.
In the first phase, all items in aItemList have their connections initialized for the given sheet (since they may have connections on more than one sheet, and each needs to be calculated individually). The graphical connection points for the item are added to a map that stores (x, y) -> [list of items].
Any item that is stored in the list of items that have a connection point at a given (x, y) location will eventually be electrically connected. This means that we can't store SCH_COMPONENTs in this map – we must store a structure that links a specific pin on a component back to that component: a SCH_PIN_CONNECTION. This wrapper class is a convenience for linking a pin and component to a specific (x, y) point.
In the second phase, we iterate over each value in the map, which is a vector of items that have overlapping connection points. After some checks to ensure that the items should actually connect, the items are linked together using ConnectedItems().
As a side effect, items are loaded into m_items for BuildConnectionGraph()
aSheet | is the path to the sheet of all items in the list |
