// Matrix class provides data storage and manipulation like a mathematical matrix.
// Current support:
//		- Basic class functionality (copying, assigning, printing, etc.).
//		- Generate matrices from vector<vector<double>>
//		- Extract value from index
//		- Insert value at index
//		- Set all elements to a number
//		- Extract SubMatrices
//		- Construct new Matrices from SubMatrices
//		- Query the matrix size
