Node is a node in an expression tree, implemented by different types (binary, urnary, func, identity, etc) qlbridge does not currently implement statements (if, for, switch, etc) just expressions, and operators

		// WriteDialect Given a dialect writer write out, equivalent of String()
		// but allows different escape characters

		// Validate Syntax validation of this expression node
		Validate() error

		// NodePb Convert this node to a Protobuf copy of it

		// FromPB Convert a protobuf presentation of node to Node.
		FromPB(*NodePb) Node

		// Expr Convert node into a simple expression syntax
		// which can be used for json respresentation
