A poor mix of gl.DEPTH and gl.BLEND, if you do use this method, ordered
rendering of objects is necessary so that you don't have far blends
blending with closer depths.
Moved files to a web_fs handler.
Added physics.js, tries to implement some type of Molecular Orbital
theory.
Added a slapdash applyGravity function.
Added bonds list to Atom, Bounded Area by moving atoms and bonds that
crossed the bound to the other side.
Visuals are triangles where vertices are atoms.
Changed visuals to only show bonded atoms as vertices.
Fixed display of bonded atoms.  Fixed electron update for "ionic
transfer".  Added Scope radius.
Changed(fixed?) some bonding mechanics.  Not done.  About to rehash the
physics.
Moved physics to use discrete fields.  Still working on gravity.
Uniform Gravfield where the origin is out of scope.
