Construct a PrettyPrinter instance. This constructor understands
several keyword parameters. An output stream may be set using the
\var{stream} keyword; the only method used on the stream object is the
file protocol's \code{write()} method. If not specified, the
PrettyPrinter adopts \code{sys.stdout}. Three additional parameters
may be used to control the formatted representation. The keywords are
\var{indent}, \var{depth}, and \var{width}. The amount of indentation
added for each recursive level is specified by \var{indent}; the
default is one. Other values can cause output to look a little odd,
but can make nesting easier to spot. The number of levels which may
be printed is controlled by \var{depth}; if the data structure being
printed is too deep, the next contained level is replaced by
\samp{...}. By default, there is no constraint on the depth of the
objects being formatted. The desired output width is constrained
using the \var{width} parameter; the default is eighty characters. If
a structure cannot be formatted within the constrained width, a best
effort will be made.
