adding Greg's solidworks model, my array surface for Tokai (approximating their 6m^2 with Sunpower cells because I know their dimensions, and a .STL of the top surface
added some files for generic array modeling: a C60 (1px = 1mm), and an array that is roughly Luminos width and maxes out the array size
Simulation: add indirect irradiance and encapsulation loss. Fixes #22 and #24.
