Description:

The nvidia compiler enforces the fortran standard that characters in namelists must have "" or ''. This pull request removes the
"string or integer namelist" option added in pull request #154. It does not remove any of the integer parameters added to to adaptive_inflate_mod in #154

The standard is:
Note 10.33, in 10.9.1.3

"A character sequence corresponding to a namelist input item of character data type shall be delimited either with apostrophes or quotes. The delimiter is required to avoid ambiguity between undelimited character sequences and object names. The value of the DELIM = specifier, if any, in the OPEN statement for an external file is ignored during namelist input "

(Note 10.36 in the f2008 standard).

  Using strings in the namelist to specify inflation flavor was added to main but not documented. Anyone who is using strings will need to revert to using integers instead, e.g.

  &filter_mod
-  inf_flavor                  = VARYING_SS_INFLATION,                       NO_INFLATION ,
+  inf_flavor                  = 2,                       0,
