Naming conventions for algebraic classes in the Coq development

Suffixes

C: OFEs
R: cameras
UR: unital cameras or resources algebras
F: functors (can be combined with all of the above, e.g. CF is an OFE functor)
G: global camera functor management
T: canonical structurs for algebraic classes (for example ofeT for OFEs, cmraT for cameras)
