All the sources

Just a quick update: We have revamped our CovidGraph page and added all the missing sources that we have incorporated in CovidGraph.
Now the page includes all the sources we use like Hetionet or Reactome
Besides our schema where some of these were already mentioned, this should give you a better picture of what kinds of data we have incorporated in CovidGraph.

We also changed how they are listed on the page to make the list more accessible (and save you from scrolling down a huge list forever). Just let them slide by automatically or use the buttons at the buttom to scroll through the list.
