Create examples vignette

[richelbilderbeek]

At, for example, a1d8693, there was an 'Examples' vignette, close to identical to the Examples markdown file.

It is removed as it gives error when building:

0.34schecking re-building of vignette outputs ... WARNING
Error in re-building vignettes:
  ...
pandoc: Could not fetch all_default.png
all_default.png: openBinaryFile: does not exist (No such file or directory)
Error: processing vignette 'examples.Rmd' failed with diagnostics:
pandoc document conversion failed with error 67

all_default.png does exists. The vignette does build locally with CTRL-K. The vignette also fails when testing the package with CTRL-SHIFT-E.

No idea how to fix this, the minimal example, travis_r_vignette_with_pics, works as expected.

No idea what confused me. I knew I had to put the pictures in the vignettes folder. Maybe some other error played a role at the same time?

It works now, as fine as expected.
