UHC.Util.ScopeVarMp
Description
A VarMp maps from variables (tvars, ...) to whatever else has to be mapped to (Ty, ...).
Starting with variant 6 (which introduces kinds) it allows multiple meta level mapping, in that the VarMp holds mappings for multiple meta levels. This allows one map to both map to base level info and to higher levels. In particular this is used by fitsIn which also instantiates types, and types may quantify over type variables with other kinds than kind *, which must be propagated. A separate map could have been used, but this holds the info together and is extendible to more levels.
A multiple level VarMp knows its own absolute metalevel, which is the default to use for lookup.
