/**
* Printing methods. A balance may be output to a stream using the
* `print' method. There is also a global operator<< defined which
* simply calls print for a balance on the given stream. There is
* one form of the print method, which takes two required arguments
* and one arguments with a default value:
*
* print(ostream, int first_width, int latter_width) prints a
* balance to the given output stream, using each commodity's
* default display characteristics. The first_width parameter
* specifies the width that should be used for printing amounts
* (since they are likely to vary in width). The latter_width, if
* specified, gives the width to be used for each line after the
* first. This is useful when printing in a column which falls at
* the right-hand side of the screen.
*
* In addition to the width constraints, balances will also print
* with commodities in alphabetized order, regardless of the
* relative amounts of those commodities. There is no option to
* change this behavior.
