Loading detections takes a very long time, and loading gaps crashes the visualization (apparently by using up all the browser application's allocated memory). There is a need to profile the entire loading process to identify performance bottlenecks, potential memory management issues, and other optimization schemes with the goals of:\r\n - [ ] decreasing load time\r\n - [ ] enabling loading of \"large' datasets (e.g. detections and gaps)"}}
