/// This file provides macros for easier construction of openCypher query AST.
/// The usage of macros is very similar to how one would write openCypher. For
/// example:
///
///     AstStorage storage;  // Macros rely on storage being in scope.
///     // PROPERTY_LOOKUP and PROPERTY_PAIR macros
///     // rely on a DbAccessor *reference* named dba.
///     database::GraphDb db;
///     auto dba_ptr = db.Access();
///     auto &dba = *dba_ptr;
///
///     QUERY(MATCH(PATTERN(NODE("n"), EDGE("e"), NODE("m"))),
///           WHERE(LESS(PROPERTY_LOOKUP("e", edge_prop), LITERAL(3))),
///           RETURN(SUM(PROPERTY_LOOKUP("m", prop)), AS("sum"),
///                  ORDER_BY(IDENT("sum")),
///                  SKIP(ADD(LITERAL(1), LITERAL(2)))));
///
/// Each of the macros is accompanied by a function. The functions use overload
/// resolution and template magic to provide a type safe way of constructing
/// queries. Although the functions can be used by themselves, it is more
/// convenient to use the macros.
