The tifList object associates tifNames with tif codes. Most
functions that call for tif argument can take either a tif code
or a tif name.
Both function are generic function with methods for ti and
tis objects, as well as a default method. tif also has
a method for ts objects.
tif returns the tif code for x, while tifName
returns a name for that code. Many of the codes have several names,
but only the default one is returned.
tif or tifName called with no arguments returns a vector
of all tif codes with names.
period returns a vector like z giving the number of
periods elapsed since the first period defined for its argument's
frequency.
