None

User stories:

1. As a user I want to be able to see a list of available operations in a box so that I know what operations I can use to build with.
2. As a user I want to be able to drag and drop an operation from the operation box to the workspace so that I can interact with them later.
3. As a developer I want to be able to link the implementation of an operation in the Python interface to a button so that the button will be an operation object.
4. As a user I want to see on a button where its ports are so that I can create a signal from it later in the workspace.
5. As a user I want to be able to drag any amount of the same type of operation to the workspace so that I can build with many of the same type of operation.
