Slight tweaks to -parse_odkmeta-
Specify -adofile- to -cscript_bcstats-.
"Type variables" are now called "comparison variables."

They already were in the help file, but now we do so in the ado-file as
well.
Slight tweaks to -parse_opt_varlists-
Added white space.
Fixed the definition of ``var'max' for -okrange()-.
Bumped version number.
Merge branch 'release-1.3.0' into develop
