manip API

An API discussed in #31
This is a spited part of #34.
This will be discussed after HTTP handler #38.

This manip API execute a full manipulation like `bin/dataprocessor`.
A test HTML is also implemented.

You can test the manipulation by standing server by `bin/server.py`.
But this server does not work now.
