## Detailed Description

### template<std::size_t N_NODES>

class imaging::SquareIntegrator< N_NODES >

Gaussian integrator on the square.

Gaussian integrator on the square [-1, 1] x [-1, 1] with *N* nodes. SquareIntegrator<2, 4> is used as element integrator in fem_2d_square_types. SquareIntegrator is currently only implemented for *N_NODES* = 4. You will rarely use this class directly, but might plug it into your own FE traits class as *integrator_t* or *boundary_integrator_t*.
