CQLChainedIdentifier class is used for parsing (not resolving)

  Class.EmbeddedObject.Property[3]
  Class.Property#'OK'

 section of a CQL identifier.  The possible sections are:

     class (optional)
     zero or more embedded objects
     property

Note:  this must handle wildcard("*"), embedded objects, arrays, symbolic
constants, etc.
