Add unit tests for Lookup quadratures.
- Lebedev
- LDFESA
- Level Symmetric
Tested features:
- Quadrature Points on unit sphere?
- Sum of weights is 4*PI ?
- Can integrate constant function with suitable accuracy?
- Is weights vector as long as nq (prescribed number of quadrature points) ?
- Is points vector as long as nq (prescribed number of quadrature points) ?
Test accuracy is 10^-4 (Lookup table values are not too accurate)
