/**
 * This is a simple replacement for org.apache.http.client.utils.URIBuilder
 * Why roll our own? Because we can't yet depend on the later versions of appache httpcomponents
 * in STS because an older version ships with Eclipse.
 * <p>
 * Mixing old-and new appache httplibs is suspected of causing this bug:
 * https://issuetracker.springsource.com/browse/STS-3647
 *
 * When Eclipse moves on to more recent versions of httpcomponents we can delete this class
 * and use its UriBuilder instead.
