reems 0.1.1

• eems.plots() now uses the distance metric recorded in eemsrun.txt to assign interpolation points to Voronoi tiles. Previously it always used Euclidean distance, even for greatcirc runs.
• eems() now defaults to distance = "greatcirc", as documented. The previous default "greatcircle" was not recognised, so default runs silently used Euclidean distance. Default results will change. Coordinates must be (longitude, latitude) in degrees; otherwise pass distance = "euclidean". Output directories labelled greatcircle were run with Euclidean distance and now give an error in eems.plots(); change their label to euclidean to plot them.
• eems() and eems.from.files() now give an error at the start of a run if distance is not exactly "euclidean" or "greatcirc". Previously any other value was silently run as Euclidean.
• With distance = "greatcirc", eems() and eems.from.files() now give an error if any coordinate cannot be (longitude, latitude) in degrees, such as projected coordinates. Swapped (latitude, longitude) columns are only caught when a value is out of range.
