Switching on LSDA+U using Dudarev's approach (LDAUTYPE=2).
LDAUL selects the l quantum number for which on site interaction is added (-1 = no on site interaction).
The U and J parameters have to be specified.
Print occupation matrices in the OUTCAR file (LDAUPRINT=2.
L, U, and J must be specified for all atomic types!
