Lebedev quadrature nodes for oder 53, 83 and 131

NOTE: The nodes and weights are currently stored as variables for ease with packaging, 
    but can be moved to text values for clarity

    To make it easier to generate the entire set of nodes and weights, they are separated by theta values
    rather than node class
        For each B node, 2 values are stored
        For each C node, 2 values are stored
        For each D node, 3 values are stored
        The entire set of nodes are generated by rotating the stored nodes around phi
