CQLChainedIdentifier class is used for parsing (not resolving)

A couple examples of a CQLIdentifier:

 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
