Shadowfinder 2.0b

Now we use object height/shadow length at a known time to identify a list of potential locations.
If you have a shadow at 2 different times, with angle A and angle B, then that change in angle for these times corresponds to a list of potential locations.
Having a section that would allow for an input like this could increase the potential use cases for the shadow finder.

In other words. Right now the inputs are:
Object height + Shadow length + known time = locations.
I propose adding a new section with the inputs
Shadow Angle 1 + Time 1 + Shadow angle 2 + Time 2 (essentially: Shadow Angle difference + Time difference) = locations
