[SoC] OSGeo's GSoC 2017 - student's timeline should integrate *Google Summer of Code 2017 Timeline*

[Helmut Kudrnovsky]

Students,

there is an offical calendar of the *Google Summer of Code 2017 Timeline*:
 
     https://developers.google.com/open-source/gsoc/timeline

with important milestones and dates like work periods and evaluation phases.

It's highly recommended to check your own timeline against this calendar and incorporate these 
milestones (work periods and evaluation phases) into your own GSoC timeline!
 

Happy coding!
The OSGeo GSoC Team
