General operator (virtual base class); operators derive from this.
k is rank, c is multiplicative constant, d_order is derivative order, pi is parity, may be Parity::even or odd. RorI may be Realness::real or Realness::imaginary. Note: You may not construct a TensorOperator. Instead, you must construct one of the derived 'operators' (there are some general ones); see operators.hpp for list of operators. Operators work by overrideing the angularCxx() functions and angularF(). c, v, and Cxx are included in radial integral.
