Metadata Support

The metadata of an image is accessed via two functions. The ltic_getNumMetadataRecords() function returns the number of metadata records in the image. The ltic_metadataRecord() function is used to extract the actual data values of a specific record.

As with the ltic_decode() call, the parameters to the ltic_getMetadataRecord() function closely mimic their C++ SDK counterparts in the LTIMetadataDatabase class.
