   I am working with @poorejc on adding this feature. I started with @EandrewJones buildDatasets() function. I tested it, it worked, and then there was a discussion on what information we actually want in the log messages. Right now this is where we are at:
   
   - We want all attributes, not just dataset attributes.
   - We only want attributes of the event target.
   - We want to parse JSON values
   
   I wanted to share this code snippet that does the above, and see what others think should be included in a log.
   
   `
   /**
    * Builds an object containing all attributes of an element.
    * Attempts to parse all attribute values as JSON text.
    * @param  {Object} e Event from which the attributes should be extracted from.
    * @return {Object} Object with all element attributes as key value pairs.
    */
    export function buildAttrs(e) {
     let attributes = {};
     if(e.target && e.target instanceof Element) {
       let i = 0;
       let attrs = e.target.attributes;
       while(i < attrs.length) {
         let val = attrs[i].value;
         try {
           val = JSON.parse(val);
         } catch (error) {}
         attributes[attrs[i].name] = val;
         i++;
       }
     }
     return attributes;
   }
   `
