4x4 - PLL Parity

All of these work with both wide (Rw or Lw) and inner turns (r/2R or l/2L). I recommend checking out what both does on the cube, as wide turns can effect pieces you might not want if you are executing these during the 3x3 phase. Thus I put both versions in my examples.

Base / Opposite

Simplest algorithm, if you don't recognize your PLL, just use this and you'll be good to go.
