                                  IOException

Reads the bus line information from the given file returning a List of BLineTable. A BLineTable is a time table for a specific line. It contains an array of BLineStop, representing the list of bus stops the line stops at.

This method must be called after readStops.

Postcondition: All stop names are known. (If an unknown name is encountered, then an exception is thrown.)

Parameters:
