2. The system of claim 1 , wherein the processor is further configured for: processing a second user input including data indicative of at least one modification to the two-dimensional matrix, based on the second user input, modifying the two-dimensional matrix to generate a modified two-dimensional matrix, and prior to processing the first user input, storing the modified two-dimensional matrix in the memory as the two-dimensional matrix.
