Class description
A piece of prettyprinter output. Instances of this class are not used directly, instead one instantiates various subclasses of this class:

•	text
•	line-break
•	block
•	inset
•	flow
•	colon

Instances of this class have the following slots:

•	start - the start of the section, measured in characters from the beginning of the prettyprinted output
•	end - the end of the section, measured in characters from the beginning of the prettyprinted output
•	start-group? - see start-group
•	end-group? - see end-group
•	style - character and/or paragraph styles to use when outputting this section. See Text styles
•	overhang - number of columns which must be left blank before the wrap margin for the prettyprinter to consider emitting this section as a short-section. Avoids lone hanging closing brackets
