These are methods for the generic functions
is, print, unitname,
unitname<- and scale
for the class "boxx" of multi-dimensional boxes.
The is method checks that the object is of class "boxx", the
print method prints a description of the box,
the unitname method extracts the name of the unit of
length in which the box coordinates are expressed, while the assignment method
for unitname assigns this unit name.
The scale method rescales each spatial coordinate of x.
For is.boxx the value is a logical.
For print.boxx the value is NULL.
For unitname.boxx an object of class "units".
For unitname<-.boxx and
scale.boxx the result is the updated "boxx" object x.
