        Creates an IndexableField whose value will be lazy loaded if and when it is used.

        NOTE: This method must be called once for each value of the field name specified in sequence that the values exist. This method may not be used to generate multiple, lazy, IndexableField instances refering to the same underlying IndexableField instance.

        The lazy loading of field values from all instances of IndexableField objects returned by this method are all backed by a single Document per LazyDocument instance.
