Spherical Harmonics m_l^1 and m_l^-1 have ofset in integral
As the title shows, there is something off in the integral for several spherical harmonics.
- Check, if function values are correct. If no, fix bug in sphericalBasis class. this should be the post Step in AssLegendre computation
Example: Squared Integration: ( 1 ) ( 1.07417 ) ( 1.00886 ) ( 0.916971 ) ( 0.991345 ) ( 1.27205 ) ( 1.00209 ) ( 0.739918 ) ( 0.994588 ) ( 0.985238 ) ( 1.03753 ) ( 0.63161 ) ( 1.00357 ) ( 1.37581 ) ( 0.968973 ) ( 0.997267 )
