*DECK MRGGET
SUBROUTINE MRGGET(IPRINT,NSOUTO,NVOUTO,NSOUTN,NVOUTN,
> IUPD,IMERGE,MIXN,ALBEDN)
*
*----------
*
*Purpose:
* Read merge options.

* License as published by the Free Software Foundation; either
* version 2.1 of the License, or (at your option) any later version
*
*Author(s):
* G. Marleau
*
*Parameters: input
* IPRINT print level.
* NSOUTO old number of surfaces.
* NVOUTO old number of regions.
*
*Parameters: output
* NSOUTN new number of surfaces.
* NVOUTN new number of regions.
* IUPD type of merge required:
* IUPD(1) for region merge and track splitting;
* IUPD(2) for surface merge;
* IUPD(3) for material modification;
* IUPD(4) for albedo modification.
* IMERGE merged position.
* MIXN new material for old regions.
* ALBEDN new surface albedo.
*
*Comments:
* Input options:
* [ EDIT iprint ]
* [ REGI (imerge(ii),ii=1,nvouto)] -> IUPD(1) > 0
* [ EXTR (imerge(ii),ii=1,-IUPD(1))] -> IUPD(1) < 0
* [ SURF (imerge(ii),ii=-1,-nsouto)] -> IUPD(2) < 0
* [ { OLDM (mixn(ii),ii=1,nvouto) | -> IUPD(3) > 0
* NEWM (mixn(ii),ii=1,nvouto) } ] -> IUPD(3) < 0
* [ ALBE (albedn(ii),ii=1,6)] -> IUPD(4) > 0
