+API tests
+==========
+
+
+Testing the restful api from a simple python client as that's what we'll be using.
+
+This test so far mostly demoes the API. We have no SRP calc in there.
+
+TODO: keep track of the cookies during login. The server uses the session to keep track of the random numbers A and B.
+
+The output of signup_and_login_wrong_password pretty well describes the SRP API:
+
+```
+POST: http://localhost:9292/users.json
+    {"user[password_salt]": "54321", "user[password_verifier]": "12345", "user[login]": "SWQ055"}
+ -> {"password_salt":"54321","login":"SWQ055"}
+POST: http://localhost:9292/sessions
+    {"A": "12345", "login": "SWQ055"}
+ -> {"B":"1778367531e93a4c7713c76f67649f35a4211ebc520926ae8c3848cd66171651"}
+PUT: http://localhost:9292/sessions/SWQ055
+    {"M": "123ABC"}
+ -> {"field":"password","error":"wrong password"}
+```
