gridLinesfunction

Makes the grid: meridians and parallels every 15 degrees (the parallels from 75 south to 75 north, the meridians to the poles), the equator brightest, the tropics and polar circles bright, the prime meridian in a warm colour. Each line is cut into pieces of at most step degrees so it keeps to the sphere.
