Quijote kNN adding (#62)
* Fix small bug * Add fiducial observers * Rename 1D knn * Add new bounds system * rm whitespace * Add boudns * Add simname to paths * Add fiducial obserevrs * apply bounds only if not none * Add TODO * add simnames * update script * Fix distance bug * update yaml * Update file reading * Update gitignore * Add plots * add check if empty list * add func to obtaining cross * Update nb * Remove blank lines * update ignroes * loop over a few ics * update gitignore * add comments
