## Set a property (field) value of an FIS structure and return the
## updated FIS.
##
## There are three forms of setfis:
##
## @multitable @columnfractions .20 .70
## @headitem Number of Arguments @tab Action Taken
## @item 3
## @tab Set a property of the FIS structure. The properties that may
## be set are: name, type, andmethod, ormethod, impmethod,
## addmethod, defuzzmethod, and version.
## @item 5
## @tab Set a property of an input or output variable of the FIS
## structure. The properties that may be set are: name and range.
## @item 7
## @tab Set a property of a membership function. The properties that
## may be set are: name, type, and params.
## @end multitable
## @sp 1
## The types/values of the arguments are expected to be:
##
## @multitable @columnfractions .20 .70
## @headitem Argument @tab Expected Type or Value
## @item @var{fis}
## @tab an FIS structure
## @item @var{property}
## @tab a string; one of 'name', 'type', 'andmethod',
## 'ormethod', 'impmethod', 'addmethod',
## 'defuzzmethod', and 'version' (case-insensitive)
## @item @var{property_value}
## @tab a number (if property is 'version'); a string (otherwise)
## @item @var{in_or_out}
## @tab either 'input' or 'output' (case-insensitive)
## @item @var{var_index}
## @tab a valid integer index of an input or output FIS variable
## @item @var{var_property}
## @tab a string; either 'name' or 'range'
## @item @var{var_property_value}
## @tab a string (if var_property is 'name') or
## a vector range (if var_property is 'range')
## @item @var{mf}
## @tab the string 'mf'
## @item @var{mf_index}
## @tab a valid integer index of a membership function
## @item @var{mf_property}
## @tab a string; one of 'name', 'type', or 'params'
## @item @var{mf_property_value}
## @tab a string (if mf_property is 'name' or 'type');
## an array (if mf_property is 'params')
## @end multitable
## @sp 1
## Note that all of the strings representing properties above are case
## insensitive.
