`comm(Cmx|_mxC)` -> `comm(_scalar_mx|_mx_scalar)`
2020-11-12It is prohibited to use `exact:` in a `Hint Extern`Kazuhiko Sakaguchi
since `exact` might call `ssrdone` which calls use of level 0 hints, potentially causing a loop in some weird cases.

- Fix implicits of `eq_map_mx`, `eq_in_map_mx`, `map_mx_id_in` and `map_mx_id`, in order to give more practical arguments first. - Generalized `map_mx_id` to take the shape f =1 id -> M ^ f = M. The previous behaviour can be recovered through `map_mx_id (frefl id)` or `[_ ^ id]map_mx_id`

2020-09-28Redefine itv_bound with BRight_if and BRInfty_ifKazuhiko Sakaguchi
2020-09-28The new interval libraryKazuhiko Sakaguchi
- `x <= y ?< if c` (lersif) has been replaced with `x < y ?<= if c'` (lteif) where `c'` is negation of `c`. This change makes statements of several lemmas (e.g., `lteif_orb`) easily comprehensible. - The first constructor `BOpen_if` of `itv_bound` has been replaced with `BClose_if` where the first argument is inverted. Now `pred_of_itv` is defined by using `lteif` instead of `lersif`. - Intervals of `T : porderType` form a `porderType` where the ordering relation is the subset relation. If `T` is a `latticeType`, intervals also form a `latticeType` where the join and meet are intersection and convex hull respectively. They are distributive if `T` is an `orderType`.

2020-09-27Putting ord1 in fintypeCyril Cohen
ord1 is in zmodp, but it does not really require the zmodType structure of 'I_n to be stated and proven if we state it with ord0. We still keep the variant in zmodp with 0 instead of ord0 (for readability purposes).
