code: public static AlgorithmiaClient client(String simpleKey, String apiAddress, int maxConnections) {
          return new AlgorithmiaClient(new SimpleAuth(simpleKey), apiAddress, maxConnections);
      }
docs: Builds an Algorithmia client that makes all requests with your API key
  If API key is null, the default client is returned, which will
  look for ALGORITHMIA_API_KEY environment variable or java property
  If no key is found, then requests will be unauthenticated which only works
  when making requests from an algorithm running within the Algorithmia cluster
  @param simpleKey API Key for simple authentication (prefixed with "sim")
  @param maxConnections max number of concurrent connections to hold open to Algorithmia
  @return an Algorithmia client
