Sometimes the user should want to use the original IAU-76/FK5 theory. In current state, it is necessary to access low level functions to do this. Hence, we should adapt rECEFtoECI and rECItoECEF(possibly rECItoECI) to provide an option to neglect the EOP corrections.
The transformations that should be feasible neglecting EOP are:
PEF <=> TOD
PEF <=> MOD
PEF <=> J2000 (this is already available in rECEFtoECI and rECItoECEF)
