Czi rendering (#10)

* add dimension selector sliders to czi view

* version doc & version bump

* cosmetic

* fix build?

* multi-dimension selection enabled in czi view

* remove the parameterized reset function of the renderer

it is not and is conceptually questionable

doc updates & some minor improvements

auto-update CZI-view when sliders are moved

set initial window size

fix windows build and msvc build

For reasons I don not comprehend, on Windows, we must include
=opencv2/core/mat.hpp= as the very last header in the =CvMatRender.hpp=.
If this is at any other position building on Windows, compilation will
break w/ all kinds of cryptic errors regarding OpenCV.

When building w/ msvc =__PRETTY_FUNCTION__= is not defined. =ILog.hpp=
now defines it. This should be revised to only be set when the
compiler is msvc. For the time being, it is considered sufficient though.
