Detailed Description

Virtual base class for defining edge-based quadratures.

Note that an "edge" is something which is codimension 2 in the SpaceDim space (in 2D, it's a point, in 3D, it's an edge, and in 4D, it's a face. This API is designed to seamlessly work in any dimensional space, as long as the coefficients have been defined correctly in the derived class.

	)		const

pure virtual

returns quadrature coefficients – intervals are from [-1,1]

dim1 and dim2 define the directions in which the edge coordinate do not vary. In other words, in 3D, if dir1=0 and dir2=1, then the edge will be constant in x and y, and will vary in z. The elements of the "location" vector in dir1 and dir2 are zeros.

Implemented in GaussianQuadrature, and NewtonCotesQuadrature.
