We need a GUI to select a river layer and extract features

[timlinux]

Problem

Implement UI to select a line layer and then generate a point layer using the rules above where for each point its type is written in an attribute field 'type' and where each point is anutomatically rendered/labeled with its type class

Proposed solution

I think as simple as this.

Expected outcome

A GUI that able to select a layer as input and output layer, and extract feautres button.

[timlinux]

@ismailsunni made a prototype like this but we decided the gui is superfluous - the implementation just runs directly on the active line layer when the stream feature extractor action is clicked.
