Default Compiler Generated Methods
(Hidden to avoid implicit creation/calling). These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called.

## Detailed Description

MatrixSpace base class, corresponding to the Matrix base class.

For each Matrix implementation, a corresponding MatrixSpace has to be implemented. A MatrixSpace is able to create new Matrices of a specific type. The MatrixSpace should also store information that is common to all Matrices of that type. For example, the dimensions of a Matrix is stored in the MatrixSpace base class.
