Improve the implementation of pywps.inout.literaltypes

[gschwind]

Overview

I used function decoration to improve the pywps.inout.literaltypes. This make the code quite nicer to read and avoid mistake when mapping types and their corresponding converter.

Hello,

I do not understand the issue with the doc, do someone can help ?

Best regards

@gschwind looks like tests are failing due to pep8 issues.

Really like this ! Would a function decorator be simpler here instead of a class ?

Run flake8 pywps/inout/literaltypes.py. There is some extra spaces on line 30.

@gschwind thanks :) Improvements (@huard) could be added with another PR.
