 Indexing to the specified remote index and download its IR binary file
     
-#### Usage
-1. Make the source code to a .jar file for your own project  
-
-2. Java API methods  
-
-Import classes:
-
-    import net.irext.webapi.model.*;
-    
-    import net.irext.webapi.WebAPIs;
-
-Get web API instance:
-
-    WebAPIs webApis = WebAPIs.getInstance();
-    
-Sign in for access id and token:
-
-    Admin admin = webApis.signIn(userName, password);
-    
-    int id = admin.getId();
-    
-    int token = admin.getToken();
-
-Fetch household appliances categories:

-
-    List<Brand> brands = webApis.listBrands(category.getId());
-
-Fetch cities (in China) for STB:

-
-    List<City> cities = webApis.listCities(provincePrefix);
-
-Fetch STB operators of a certain city:
-
-    List<StbOperator>; operators = webApis.listOperators(cityCode);
-
-Fetch remote indexes of a certain brand or STB operator:
-
-    List<RemoteIndex> remoteIndexes = webApis.listRemoteIndexes(category.getId(), brand.getId(), city.getCode(), operator.getOperator_id());
-
-Download IR binary for certain remote index:
-
-    InputStream is = webApis.downloadBin(remoteIndex.getRemote_map(), remoteIndex.getId());
-
