-%% 1.1: 10 January 2018: new style for the map outer box. Support for

-%% New keys to enable indices and disable bars. Macro file renamed

-%% First, we have to introduce some counters:

-%%
-%% The \kmindexcounter is needed for the indices in the fields of the

-%%
-\newcount\kmindexcounter
-%%
-%% \kmxsize and \kmysize store the dimensions of an entire diagram.
-%%
-\newcount\kmxsize
-\newcount\kmysize

-%% Some counters are necessary to compute the bars for the variable
-%% identifiers:

-\newcount\kmbarstart
-\newcount\kmbarlength

-%% process the variable-length parameters in \karnaughmap:

-%% The macro \kmsetoptstr reads one token from the list of parameters in
