Generalize DragEndedListener

• [x] create function to check a particle is within a square area and pass boolean back to listener

Periodic Table

• [x] colors to match between "highlight cell" and periodic table cell

Stable nodes

• [x] Energy label
• [x] shell model title
• [x] dotted lines on atom

Mini particle atom and energy levels

• the mini nucleus is the ParticleAtom
• the energy level represent the pseudo particle atom
• send particles in, don't add to ParticleAtom.
• send particles in to ParticleAtom with BANScreenView.addNucleonImmediatelyToAtom()
• create parallel array of protons and neutrons that would hold pseudo particles
  • link to ParticleAtom so any change in energy levels reflected in ParticleAtom
  • energy play area level node determines:
  • capture area
  • nucleon placement
  • holds pseudo particle nodes

Steps:

• [ ] energy level node to define capture area
  • [ ] energy levels model (keeps track of particles and levels they're at - one model for each protons/neutrons)
    • [ ] y = 0 (lower level) , 1, 2 (higher level)
    • [ ] at y=0, x = 2, 3 ; y = 1 x = 0 - 5, y = 2, x = 0 -5
  • [ ] energy levels view ( each node grabs position info from model)
• [ ] define nucleon placement and define array of parallel protons and neutrons
• [ ] set ParticleAtom as mini nucleus
