NumberConverter implementation that handles conversion to and from java.lang.Double objects.

This implementation can be configured to handle conversion either by using Double's default String conversion, or by using a Locale's pattern or by specifying a format pattern. See the NumberConverter documentation for further details.

Can be configured to either return a default value or throw a ConversionException if a conversion error occurs.
