Refactored calculation functions to combine and simplify logic.
Revised functions to accept direct parameters instead of operating on the entire grid.
Resulted in significant performance improvements through enhanced compiler optimization.

Modified the createSolutionVector function to use matrix operations
Additionally added a function to create the entire solution matrix.
This function, whilst currently active, is better suited for GPU usage.

Using matrix operations wherever possible
Added support for multithreading
Moved simulation loop into BTCS to minimize memory allocation
Switched to Tridiagonal Coefficient Matrix
