Improve reduction transformation

  • make the difference between reduction over geometry or reduction between process.
  • geometrical reduction :

domain -> axis
axis -> scalar
domain -> scalar

  • reduction across processes for redondant geometrical cell :

axis -> axis
scalar -> scalar

Reduction can be local (only for the geometrical cell owned by current process) or global, using the "local" attribute (bool) over the reduction.
