====== ReadFPLOBasisFunctions ======

###
ReadFPLOBasisFunctions(orbitals,file1,file2) reads the files specified by file1 and file2 that contain the wavefunctions obtained from the FPLO DFT calculation and returns interpolating functions corresponding to the names given by orbitals.
###

===== Input =====

  * orbitals : list of string
  * file1 : string
  * file2 : string - optional - if given, relativistic wave functions are assumed where the large part is contained in file1 and the small part in file2

===== Output =====

  * list of InterpolatingFunction : large part of the wavefunctions if file2 is given, otherwise non-relativistic wave functions
  * list of InterpolatingFunction : small part of the wavefunctions if file2 is given, otherwise NULL

===== Example =====

###
For non-relativistic wave functions the orbitals are labeled "nl" where n is the principle quantum number and l is the letter corresponding to the angular momentum quantum number. For relativistic wave functions the orbitals are labeled "nlj" where j is the total angular momentum quantum number.
