## Add new parameter to the object @var{parser} of the class inputParser to implement
## a name/value pair type of API.
##
## @var{argname} must be a string with the name of the new parameter.
##
## @var{default} will be the value used when the parameter is not specified.
##
## @var{validator} is an optional function handle to validate the given values
## for the parameter with name @var{argname}. Alternatively, a function name
## can be used.
##
## See @command{help inputParser} for examples.
