BlockDavidsonInitFailure is thrown when the BlockDavidson solver is unable to generate an initial iterate in the BlockDavidson::initialize() routine.
This exception is thrown from the BlockDavidson::initialize() method, which is called by the user or from the BlockDavidson::iterate() method if isInitialized() ==
In the case that this exception is thrown, BlockDavidson::isInitialized() will be
false and the user will need to provide a new initial iterate to the solver.
