Retrieve values stricktly implied by rules

Detects cases where two inequalities imply an equality, e.g. *x≤q 0* and *x≥q0*
implies *x=0*. Also detects straight equalities, e.g. *x==0* implies *x=0*. Such
cases arise frequently when manipulating edits by value subsitution or variable elimination.
The function recursively detects equalities and combined inequalities that imply fixed values,
substitutes those fixed values and looks for new implied values until no new values are found.
