Title: New Ring opening/closing reaction classes

These new reaction families are added for primary ring opening reactions:
1- Intra_RH_Add_Exocyclic: Ring opening through tautomerization (H-migration and double bond formation)

2- Intra_RH_Add_Endocyclic: Ring opening through tautomerization (H-migration and double bond formation)

3- Intra_R_Add_ExoTetCyclic: Baldwin's exo-tet ring opening reaction class

Still kinetic data is needed to fill the database for new families.
