/**
* {@link PrettyPrinter} implementation that adds no indentation,
* just implements everything necessary for value output to work
* as expected, and provide simpler extension points to allow
* for creating simple custom implementations that add specific
* decoration or overrides. Since behavior then is very similar
* to using no pretty printer at all, usually sub-classes are used.
*
* Beyond purely minimal implementation, there is limited amount of
* configurability which may be useful for actual use: for example,
* it is possible to redefine separator used between root-level
* values (default is single space; can be changed to line-feed).
*
* Note: does NOT implement {@link Instantiatable} since this is
* a stateless implementation; that is, a single instance can be
* shared between threads.
