/*
NewFormatter returns a custom formatter that satisfies the fmt.Formatter
interface.  As a result, it integrates cleanly with standard fmt package
printing functions.  The formatter is useful for inline printing of smaller data
types similar to the standard %v format specifier.

The custom formatter only responds to the %v (most compact), %+v (adds pointer
addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
combinations.  Any other verbs such as %x and %q will be sent to the the
standard fmt package for formatting.  In addition, the custom formatter ignores
the width and precision arguments (however they will still work on the format
specifiers not handled by the custom formatter).

Typically this function shouldn't be called directly.  It is much easier to make
use of the custom formatter by calling one of the convenience functions such as
Printf, Println, or Fprintf.
