 =======================
-Currently, metric solutions are packaged by specifying four key parameters and storing them in an array. These paramaters include the index configuration for the given metric solution, the coordinates to define the metric in terms of, the metric and the cosmological constant. Below represents a valid definition of the Schwarzschild stationary black hole solution.
