Documentation plotMAP

[mafla]

Keyword arguments in plotMAP is incomplete. Would be nice to know from the documentation that one can also use plotMAP(c, xaxis = "MSC", yaxis = "Lon") or so.

If you look at the documentation ?plotMAP it is already mentioned that there is an xaxis and yaxis keyword. Do you suggest to add an example here: http://esa-esdl.github.io/ESDL.jl/latest/plotting.html

Ah, now I see. The documentation on the github pages was outdated and did not have the xaxis and yaxis keywords yet. Will fix this.
