csLink

The widget csLink provides users with the opportunity
to not only explore a single letter of an online editon but also its interconnection
with other letters from the same letter network.

The widget can be included in an online edition to generate a link "Explore Network of Letters".
Depending on the values of the data- attributes, an overlay will pop over on
hovering the link and show a maximum of two other letters from the letter network.

In addition, links are provided to a complete list of the search query on http://www.correspSearch.net.
If a letter entry contains a valid URL reference, the search result will be linked
to the letter in its respective online edition.

In version 1.0.2, further bugs with the median calculation have been fixed.
