DESCRIPTION
       Provides a snit class whose instances manage a key/value map.  In other
       words, an object wrapper around Tcl arrays.

API
       The main command provides construction of maps:

       ::struct::map mapName
              Creates a new, empty map with an associated global  Tcl  command
              whose  name is mapName.  It may be used to invoke various opera-
              tions on the map.  It has the following general form:

              mapName method ?arg arg ...?
                     method and arguments determine the exact behavior of  the
                     command.

              If  mapName  is specified as %AUTO% a unique name will be gener-
              ated by the package itself.  The result of the  command  is  the
              fully-qualified name of the instance command.

       The following commands are possible for map objects:

       mapName get
              Returns the entire map as a Tcl dictionary.

       mapName names
              Returns  the list of all keys known to the map, in arbitrary or-
              der.

       mapName set name ?value?
              Sets key name to the specified value, if  the  value  specified.
              Returns  the  value  for the key.  Throws an error if the key is
              not known.

       mapName unset ?pattern...?
              Removes all keys matching at least one of the glob patterns from
              the  map.   If no pattern is specified all keys are removed.  In
              other words, the default pattern is *.  The result of  the  com-
              mand is the empty string.
