 *
 * The path identifies a specific resource on the host. Paths have a hierarchical structure like
 * "/square/okhttp/issues/1486" and decompose into a list of segments like `["square", "okhttp",
 * "issues", "1486"]`.
 *
 * This class offers methods to compose and decompose paths by segment. It composes each path
