photobiology 0.9.16

The main changes from version 0.9.15 the previous CRAN release, are:

Revise the code for all solar-position-related calculations to improve computation speed when arguments are vectors. The returned values and their high precision remains the same as in recent versions, but when called with long vectors of times or dates, performance is orders of magnitude faster than in earlier versions. Revise documentation. Fix some minor bugs in example sensor data.

Rename color() method to color_of() to avoid name clashes. Define a function color() to maintain backwards compatibility. Define colour_of() to provide synonym for British spelling.
