      Add GNSS antenna footprint including correct 50Ohm feed line dimensions and keepout area, add u-blox MAX-8 3D model, rename all instances of MAX-M8* to MAX-8* due to part selection, antenna feed line calculatos included (coplanar waveguide)
      
      Need to add placeholder footprints for the other four antennae which will be represented as simple rectangular areas where the antennae will occupy. After that, all that is left is to assign the various remaining IC footprints and finally import all footprints into PCBNew & begin layout!

      Replace the AP22800 load switch with the P-channel AP22814 load switch IC due to its reverse current & over current protection capability, add level shifter circuit to the WWAN's DPR signal
      
      Reverse current is no longer an issue with the load switches. One more obvious "TODO" for the schematic left which is to simply place several 100nF bypass caps on the 5V_P, 3V3_P, and 1V8_P rails (investigate how EmCraft is placing these in their layout).
