+Description: 1. Generality
+        
+        Dataset maker is morphemic python library for 
+        building dataset from data points registered into InfluxDB.
+        Dataset maker receives the name of an application, the start time 
+        and the tolerance interval. More details are provided below.
+        
+        2. InfluxDB format 
+        
+        Data points in InfluxDB should have the following format for being used
+        correctly by the dataset maker:
+        
+        measurement : "application_name" #mandatory 
+        timestamp : timestamp #optional
+        fields : dictionnary containing metric exposed by the given application 
+                 cpu_usage, memory_consumption, response_time, http_latency
+        tags : dictionnary of metrics related information
+        
+        The JSON describing the above information is the following:
+        
+        Ex.: 
+            {"measurement": "application_name", 
+              "timestamp": 155655476.453,

+            }
+         
+        If data points are presented as the above format, the dataset maker will output 
+        a csv (application_name.csv) file with the following schema:
+        time, cpu_usage, memory_consumption, response_time, http_latency, core
+        
+        3. Usage

+1. Generality
+
+Dataset maker is morphemic python library for 
+building dataset from data points registered into InfluxDB.
+Dataset maker receives the name of an application, the start time 
+and the tolerance interval. More details are provided below.
+
+2. InfluxDB format 
+
+Data points in InfluxDB should have the following format for being used
+correctly by the dataset maker:
+
+measurement : "application_name" #mandatory 
+timestamp : timestamp #optional
+fields : dictionnary containing metric exposed by the given application 
+         cpu_usage, memory_consumption, response_time, http_latency
+tags : dictionnary of metrics related information
+
+The JSON describing the above information is the following:
+
+Ex.: 
+    {"measurement": "application_name", 
+      "timestamp": 155655476.453, 
+      "fields": {
+          "cpu_usage": 40,
+          "memory_consumption": 67.9,
+          "response_time": 28,
+          "http_latency": 12
+      },
+      "tags": {
+          "core": 2 #cpu_usage of 40% is the usage of the cpu core number 2
+      }
+    }
+ 
+If data points are presented as the above format, the dataset maker will output 
+a csv (application_name.csv) file with the following schema:
+time, cpu_usage, memory_consumption, response_time, http_latency, core
+
+3. Usage 
+
+
+Warming : make sure the above variables exist before importing dataset make library
+
+from morphemic.dataset import DatasetMaker 
+
+data_maker = DatasetMaker(application, start, configs)
+response  = data_maker.make()
+
+application, string containing the application name 
+start, when to start building the dataset 
+Ex.: '10m' , build dataset containg data point stored the 10 last minute
+Ex.: '3h', three hours 
+Ex.: '4d', four days 
+leave empty or set to None if you wish all data points stored in your InfluxDB
+configs is dictionnary containg parameters
+
+{
+    "hostname": hostname or IP of InfluxDB
+    "port": port of InfluxDB
+    "username": InfluxDB username 
+    "password": password of the above user 
+    "dbname": database name 
+    "path_dataset": path where the dataset will be saved
+}
+
+the response contains
