QD dependencies (Windows)

[yn-coder]

Trying to build the lib with MS VS and got Could not find QD message.

README says

Required Dependencies:
...
 - libqd-dev             http://crd.lbl.gov/~dhbailey/mpdist/

Is libqd-dev are https://www.davidhbailey.com/dhbsoftware/ QD lib ? Does it have a Windows version?

[aewallin]

there seems to be a Windows build of libqd here:
https://github.com/aoki-t/libqd

I don't know if there's a binary installer or if you need to build it from source on Windows.

Travis-CI can now run builds & tests on Windows (and Mac OSX)- so it would be good to build openvoronoi on all the platforms that travis supports.
