/**
 * A builder that can be used to construct a twitter4j configuration with desired settings.  This
 * builder has sensible defaults such that {@code new ConfigurationBuilder().build()} would create a
 * usable configuration.  This configuration builder is useful for clients that wish to configure
 * twitter4j in unit tests or from command line flags for example.
