GESun - To know "how much" a point on Earth is sun lit at a given timestamp + Programmatic acces to the sun slider + event sun slide

[GoogleCodeExporter]

Implementation suggestion over the GESun interface :

The leading idea is to "convert sun shade on Earth" into physical values for a 
given timestamp.

- Link the annual and daily sun course and rays to a given point on Earth at a 
given timestamp, to know if yes or not this point is sun lit, according to the 
neighbouring DEM to ensure of the direct, diffuse or reflected exposition. So 
one could think about float values in kW/m² ... but the greatest addendum 
could simply be a point geometry property to know the max theorical sunlight 
duration (hours per year, month, week, day) according to the surrounding relief 
and the sun height ...

+ sun event onslide (timestamped) to play with these values

*** stared Issue 99:    Real Time Sun Shadow Position 
* Issue 104:    Allow date change for Sun feature

I forgot to mention the BUILDINGS which is often the first obstacle to sun 
light. There could be a way to know if a given point where there is a 3D 
building, is hit, and again how much, by the sun rays ...
