Print Basic Facts about a TransferFunction
Each TransferFunction object is actually a list of so-called elementary transfer functions;
for details on this see composition().
This print() calls an internal print() function for each elementary function individually.
The internal print() also calls an
internal validate() (with default arguments) which runs some basic tests
and formats the results nicely for printing, see validate().

The function returns TRUE or FALSE.
