Matt Juntunen created GEOMETRY-125:
--------------------------------------

             Summary: DoubleFormats Builder
                 Key: GEOMETRY-125
                 URL: https://issues.apache.org/jira/browse/GEOMETRY-125
             Project: Apache Commons Geometry
          Issue Type: Improvement
            Reporter: Matt Juntunen


Use a {{Builder}} class in {{DoubleFormats}} to make the API more self-documenting. Ex:
{code:java}
// current
DoubleFunction<String> def = DoubleFormats.createDefault(5, -3);
DoubleFunction<String> sci = DoubleFormats.createScientific(5, -3);

// new
DoubleFunction<String> def = DoubleFormats.builder()
    .withMaxPrecision(5)
    .withMinExponent(-3)
    .build();

DoubleFunction<String> sci = DoubleFormats.builder()
    .withMaxPrecision(5)
    .withMinExponent(-3)
    .buildScientific();
{code}
