Input: A touch friendly mobile app for data collection (foss4g2019)

Data collection is an essential part of most GIS users. There are several mobile apps (open source and proprietary) which can be used carry out such tasks. We have extended QGIS libraries to take advantage of [QT Quick framework](https://doc.qt.io/qt-5/qtquick-index.html) and introduced [QGIS Quick library](https://github.com/qgis/QGIS-Enhancement-Proposals/issues/109). QGIS Quick library has become a part of the official QGIS project and it adds the possibility to create custom mobile apps. Just like plugin architecture for desktop QGIS allows great flexibility to introduce custom functionality, QGIS Quick library provides similar groundwork for mobile mapping apps. [Input](https://github.com/lutraconsulting/input) a free and open source mobile app has been developed, leveraging on the new QGIS Quick library.
