Code cleanup

[epsi1on]

I did some cleanup to the code files. here is details:

• Move examples files into Examples folder in the root
• Combined .sln files of example (there where a single .sln file for each individual example)

All in all there where about 8 sln files, 7 for examples and 1 for library itself. now there is three, one for library, one for wpf examples and one for uwp examples

TODO:
examples are grouped into three sln files: WPF, UWP and WinRT. i was not able yet to create solutions for UWP and WinRt

almost no change to the source codes, files are just moved

hi @reneschulte
Could you please give me a comment about this PR?
I tried to create a fork of WBEX in order to fix the alpha issue (#95) but there still exists a fork which relates to this PR.
I need to know whether continue this fork or discard changes and create new one.

Thanks

Honestly I'd like you to create a fresh one for #95 based on the main branch. This #93 is a bit too much files changes. I'm worried about regressions at this point.
