Inverse Lambert projection.

1	invlambert(x, y, lat0, lon0, lat1, scale = "km", old = F)

`x,y`	The input data to be inversely projected as two vectors
`lat0`	First latitude defining of the projection
`lon0`	Longitude defining the projection
`lat1`	Second latitude defining the projection
`scale`	Scale of the input data, "km" default, redundant ??
`old`	Old method, seldom used???

List of components:

`lat, lon`	Coordinates in latitude and longitude
`x, y`	Input coordinates (projected)
`scale`	Scale
`projection`	Projection (stated redunantly)
`lat0, lon0, lat1`	Defining lats and lon
