Knowing the sunrise and sunset time maybe important information for applications that depend on whether it is day or night.

The sunset or sunrise time information may useful for something like giving the appropriate salute to an user given the current time of the day, or other more complex situations that depend on knowing whether it is day or night where an user lives.

The calculation of the sunrise and sunset is not trivial. It depends on the geographic coordinates of the place in the world being considered, the day of the year and the position criteria that determines exactly when it is considered to start the sunrise or sunset.

This class provides a solution that simplifies that problem by making the correct calculations considered all the important factors.

Detailed description

This class contains methods for calculating the sunrise and sunset for any day, for any zenith (angle at which the sun is said to rise or set) and any place in the world given its latitude and longitude coordinates.

Please note that the algorithm used for the calculations are not mine. The algorithm was taken from http://williams.best.vwh.net/sunrise_sunset_algorithm.htm (without permission). There are many algorithms for calculating sunrise/sunset, but this was the simplest and explained in an easy to understand manner.
