SETTURTLENAME takes a turtle number and a word as input and assigns that name to the given turtle. After naming turtles, you can refer to them by their numbers or names.

TURTLENAME reports the name of the current turtle. TURTLENAMES reports a list of all turtle names. Turtles have a default name of the form TURTLE.n, where n is the turtle number.

Note that a turtle can have a quoted name and its shape can have a dotted variable name.
