/** Class for representing an identifier.
 *
 * This can still be multiple things like:
 * - name of alias, schema, table and or column
 * - name of function
 * - predefined symbol like LOCAL_TIME
 *
 * During parsing this cannot always be determined as an alias might be involved that hasn't been parsed yet
 * so we put a Identifier in the AST a follow up pass could determine what it actually as and act appropriatly
 *
 * An identifier can consist of following fields
 *	- [[schema.]table.]column
 *	- [alias.]column
 *  - [schema.]table.function (for function taking a row of type table)
 *  - alias.function (for function taking a row of type table)
 *  - schema.function
 *  - sql symbol like CURRENT_DATE
