solution was to check if the state_to_load's matrices are empty before loading them in.
issue was with the reshape command, which couldn't be done on an empty matrix. I don't think we need any kind of error handling (for reshape() specifically) because we are the one's saving the matrices and they are only set & saved with the correct # of values.
closes #22
