setTileNamingConvention()

void ossimIgenGenerator::setTileNamingConvention ( const ossimString &  namingConvention )

Tile naming convention is a string that can be "id" or "usgs". this is used if tiling is enabled. If id is used it will use the filename as the prefix and then add to it the id's. If usgs is used it will name it based on the USGS name.
