This file clones part of ssralg hierachy for countable types; it does not cover the left module / algebra interfaces, providing only countZmodType == countable zmodType interface. countRingType == countable ringType interface. countComRingType == countable comRingType interface. countUnitRingType == countable unitRingType interface. countComUnitRingType == countable comUnitRingType interface. countIdomainType == countable idomainType interface. countFieldType == countable fieldType interface. countDecFieldType == countable decFieldType interface. countClosedFieldType == countable closedFieldType interface. The interface cloning syntax is extended to these structures [countZmodType of M] == countZmodType structure for an M that has both zmodType and countType structures. ... etc This file provides constructions for both simple extension and algebraic closure of countable fields.
