Changes since 1.11: +24 -13 lines 
add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
 between tiles, just fill-in edges assuming locally periodic subdomain) and
 add corresponding exchange subroutines (EXCH0);

20 C | SUBROUTINE EXCH_UV_XY_RX
21 C | o Handle exchanges for _RX, 2-dimensional vector arrays.
22 C *==========================================================*
23 C | Vector arrays need to be rotated and interchaged for
24 C | exchange operations on some grids. This driver routine
25 C | branches to support this.
