[CP2K:5031] Implementing new functionals

I had a quick look at this functional and it seems to me there
are three non-trivial things to do for the implementation in

1) add a new parametrization to the BECKE97 functional
   follow the lead from other parametrizations
2) add a new potential type in the HF section
   follow the lead from other mixed potential types in the code
3) check if the implemented rVV10 functional can be used instead
   of the original VV10. Only rVV10 is implemented in CP2K

Your input will look something like this:

        SCALE_X 0.0
        SCALE_C 1.0
      &END PBE
          EPS_SCHWARZ 1.0E-3
          OMEGA 0.11
          MAX_MEMORY  10
        FRACTION 0.25
           TYPE RVV10
           PARAMETERS 6.3 0.0093
           KERNEL_FILE_NAME ../rVV10_kernel_table.dat
           CUTOFF  80
         &END NON_LOCAL
    &END XC

I would like to implement the ωB97X-V functional as presented in this paper: http://www.ncbi.nlm.nih.gov/pubmed/24430168
I am relatively new to CP2K so I apologize if this is a trivial question, but would someone mind assisting me in implementing this functional?
