Add a way to share examples in live editor

allow user to share exemple within live editor would be helpfull.
As a reference point the editor offered by within the site of ramdajs is pretty neat

Start by locating the live editor entry point and any existing example-handling flow in the repository. Use the Ramda live editor mentioned in the issue as a reference, then define what sharing an example should produce and verify that an example can be shared from the editor and opened or reproduced by another user.
