10 years ago- lazy extended reduction parked

- lazy extended reduction parked
- fpns finally removed
- "big tree" computation based again on "full" extended reduction
  but improved with lazy equivalence for local environments
- llor parked for now (something to fix there)

10 years agowe restored the strong normalization of extended computation for local

we restored the strong normalization of extended computation for local

10 years ago- some work on extensions:

- some work on extensions:
  the alternative definition of lpx_sn and llpx_sn is useless since it is recursive
  llor seems to contain a bug in the referred components
- some work pointwise extended reduction:
  we restore the "full" version and use it for the normaliztion of extended reduction
  we still use "lazy" version for the "big-tree" theorem
