 ### Methods
+- `putContainer(params)`. The `params` is a dictionary (e.g. 
+  `{acl:'public-read-write',placement_policy:'REP 3',name:'container-name',name_global_scope:'false'}`). 
+  Returns dictionary with `success`
+  boolean flag, `container_id` string, and `error` string.
 - `setBufferSize(size)`. Sets internal buffer size for data upload and 
   download. Default is 64 KiB.
 - `put(container_id, headers, payload)`. Returns dictionary with `success`
