Add the GlySTreeM: examples as they are today.

TODO:

• Used the titles as rdfs:comment, should we change this? For now lost the comments.
• Identifiers, given three paths in the urls .well-known/sparql-examples might not be the best

Note that when trying to execute a query with https://yasgui.triply.cc/ to https://glyconnect.expasy.org/glystreem/sparql we get Error (#502) Bad Gateway

But sending a query directly in the URL query param works:
https://glyconnect.expasy.org/glystreem/sparql?query=SELECT%20*%20WHERE%20%7B%3Fs%20a%20%3Fo%7D%20LIMIT%2010

It would be good if the comments included in the original files could be added as some explain what variables can be changed to make the queries useful with a users own data. There are some comments that are quite long, but I can try & make them more concise if needs be?
