16                  the identifier portion of a CQL select statement.  
17                  A couple examples of a CQLIdentifier:
18                  
19                    Class.EmbeddedObject.Property[3]
20                    Class.Property#'OK'
21                  
22                  
23                  The CQLChainedIdentifier class can parse and return each
24                   section of a CQL identifier.  The possible sections are:
25                  
26                       class (optional)
27                       zero or more embedded objects
28                       property
29                  
30                  Note:  this must handle wildcard("*"), embedded objects, arrays, symbolic
31                  constants, etc.
