Each object, i.e. Vector, Matrix, Grid, etc., needs to have an attribute called "_info", which will be a string containing pertinent temporary information. For example, if a matrix multiplication fails, the object it was called on will log a message in _info so that a logging system can extract the relevant information and record it.
