This is not an actual bug rather an expected behaviour as documented in
http://dev.mysql.com/doc/ndbapi/en/ndb-ndboperation-methods.html#ndb-ndboperation-equal
This patch adds two examples demonstrating insertion and reading from
[VAR]CHAR/BINARY columns.
changes
 - added an array adapter class that helps in converting input for above said 
 	 columns to required aRef format
 - added an example - ndbapi_array_simple that inserts and retreives without
   using the array adapter
 - added an exampke - ndbapi_array_using_adapter that uses the array adapter
   to insert and read data
 - modified the ndbapi-examples.test to include the above two examples
