Adds basic tally library cmake files

Commenting out unit tests for now, but these changes will build dagtally.so library.  Also updated the KDENeighborhood/TrackLengthMeshTally kd-tree calls to reflect the moab version.  Note that this will compile with moab 4.6.3 but KDE unit tests do not all pass.  It will not compile with moab 4.6.0 because for some reason moab/Version.h does not exist in moab/include.
