-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 itself and the cosmological constant.

+Currently, all metric solutions are packaged by specifying four key parameters and storing them in an array. These paramaters include an index configuration for the given metric solution, the coordinates to define the metric in terms of, the metric itself and the cosmological constant. It is important to note that a zero-valued cosmological constant indicates the employment of a classical formulation to the Einstein filed equations. Below represents a valid definition of the Schwarzschild stationary black hole solution.

+It may be helpful to store the solutions in a separate module. I prefer to keep my solutions in a 'Solution()' class which can be found in the 'solutions' module.

 The index configuration in this case is "dd" which represents a down-down configuration which reflects a double covariant index configuration. These can be "uu", "dd", "ud", "du" but this library currently only supports certain index configurations depending on the quantity in question.

 =============================
-The Einstein field equations describe the equivilence of space-time curvature to mass-energy. The mass-energy is described by the coefficents encompassed within the stress-energy-momentum tensor denoted by T_{\mu\nu}. The cosmological constant denoted by Lambda is treated as an input parameter (since it is independent of the metric in most cases) and represents the dark energy thought to be responsble for the accellerated expansion of the cosmos.
