    31 * Refinements to lattices classes:
       
    32   - added boolean_algebra type class
       
    33   - less default intro/elim rules in locale variant, more default
       
    34     intro/elim rules in class variant: more uniformity
       
    35   - lemma ge_sup_conv renamed to le_sup_iff, in accordance with le_inf_iff
       
    36   - dropped lemma alias inf_ACI for inf_aci (same for sup_ACI and sup_aci)
       
    37   - renamed ACI to inf_sup_aci
