/** 
  The CQLIdentifier class encapsulates
  the different formats of the CQL property portion
  of a CQLChainedIdentifier. 

  For example, a CQLChainedIdentifier can have these parts:
 
    Class.EmbeddedObject.Property
    Class.Property


The "Property" portion of the CQLChainedIdentifier can be
in any of these 3 formats:
   (a)  property name
   (b)  property[3]     e.g. an array index
   (c)  property#'OK'    e.g. a symbolic constant
   (d)  *   (wildcard)

In the future, there may be support added for a set of indices (ranges).
