Detailed Description

Converts the x and y indices of tiles to and from geo coordinates.

For tiles of maps in Equirectangular projection.

Tiles do have the same width and the same height per zoomlevel. The number of tiles per dimension is twice that of the previous lower zoomlevel. The indexing is done in x dimension eastwards, with the first tiles beginning at -180 degree and an x value of 0 and the last tiles ending at +180 degree, in y dimension southwards with the first tiles beginning at +90 degree and a y value of 0 and the last tiles ending at -90 degree.
