+*-----------------------------------------------------------------------
+*
+*Purpose:
+* Compute the number of homogenized/condensed isotopes in the output
+* microlib.
+*

+*
+*Author(s): A. Hebert
+*
+*Parameters: input
+* NBISO   number of isotopes in the input microlib.
+* ISONAM  local names of NBISO isotopes:
+*         chars 1 to 8  is the local isotope name;
+*         chars 9 to 12 is a suffix function of the mix number.
+* MIX     mixture number associated with each isotope.
+* IPRINT  print index.
+* NREGIO  number of volumes.
+* NMERGE  number of merged regions.
+* MATCOD  mixture index per volume.
+* IMERGE  index of merged regions.
+* LSISO   flag for isotopes saved.
+* LISO    =.TRUE. if we want to keep all the isotopes after 
+*         homogeneization.
+*
+*Parameters: output
+* MAXISO  number of homogenized/condensed isotopes in the output
+*         microlib.
