[Maposmatic-dev] [PATCH 2/6] Implement a skeleton /papersize/ service

[Thomas Petazzoni]

This service receives by post either a (osmid, layout) or a (bbox,
layout) and is responsible for asking OCitySMap what are the possible
paper size for the given geographic area. As OCitySMap doesn't
implement this feature yet, it is only a skeleton that returns a fixed
set of paper sizes.
