C# Класс RegexParser.Transforms.QuantifierASTTransform
An Abstract Syntax Tree (AST) transform that converts quantifiers to their canonic form: - quantifier {n,m} becomes pair {n,n}, {0,m-n} - quantifier {n,} becomes pair {n,n}, {0,} - quantifiers already in target form ({n,n}, {0,m}, or {0,}) remain unchanged
