Transfer of Heat by Thermal Radiation

Calculates the Incident Heat Flux on a receiving surface using pre defined configurations. center aligned can be used when the point of reference is in the center of the emitting surface. Corner aligned when the point of reference is in the corner of the emitting surface. When neither work perfectly, we can split the emitting surfaces into smaller parts and apply the appropriate alignment to each part. Adding and subtracting appropriately.
