LoadFCalGeometryFromFiles function was removed from CaloGeometry class in !21722 (merged). However, this function is still needed in tools/CaloGeometryFromFile.cxx. I assumed by mistake that the function is also in this function. I am adding this missing function in there.
tools/CaloGeometryFromFile class is not used by any athena classes and it is not even compiled in athena. It is just required in local runs outside athena. It will be removed from athena repository soon but we still need to have it working for some time.
