Mini query provider

Implement static string Translate(Expression<Func<int, bool>> predicate) that walks the tree and produces a pseudo-SQL WHERE clause: GreaterThanOrEqual → ">=", LessThan → "<", Equal → "=", AndAlso → "AND", OrElse → "OR", with the parameter rendered as "x" and constants as their value. Example: x >= 5 renders "x >= 5"; (x >= 5) AND (x < 100) renders "x >= 5 AND x < 100".
