Extend method metadata #4
Description
Currently, only the size and degree of quadrature methods are tabulated.
In some usecases, it is desirable to select a quadrature method based on additional properties, e.g. the symmetry of the sampling points or the arithmetic precision. Hence, it would be good to extend the properties that is tabulated with the quadratures, such that these can be used for quadrature selection)
I propose that at least the symmetry should be tabulated. Additional properties could be the available precision of quadrature points and weights and possibly other properties special to the method.
