/**
 * The method orders the passed images by their location ordered by rows.
 * The sort algorithm is based on MGRS (Military grid reference system) 
 * definition (See
 * https://en.wikipedia.org/wiki/Military_grid_reference_system for 
 * details).
 * Tile ID is composed by the following pattern: _TXXXxx (5 x), these 'x' 
 * define MGRS location as followed:
 *   XXX: Grid Zone Designation (UTM zone + latitude letter C-X omitting 
 *      I and O)
 *   xx: the 100,000-meter square identifier. 100km square inside the GZD.
 *      The identification consists of a column letter (A–Z, omitting I 
 *      and O) followed by a row letter (A–V, omitting I and O).
 *      
 *   i.e: S2A_OPER_MSI_L1C_TL_SGS__20150621T042634_A005374_T17UPU_B01.jp2
 *   or   S2A_OPER_PVI_L1C_TL_SGS__20150621T042634_A005374_T17UPU.jp2
 *   The MGRS designator is located at [50-55]
 *   
 *   The use of TreeMap ensure keys are lexicographically ordered and 
 *   keep in memory the key as the grid zone descriptor, row index and 
 *   column index in this reference. 
 * @param image the image add
 * @return -1 if image insertion not possible, 0 otherwise.
