Details:

polysplit and polyjoin are two functions that do the reverse of each other. In
MATLAB they are part of the vector data analysis section of the mapper toolbox
package. I have written an implementation for each polysplit and polyjoin

polysplit:
converts line or polygon parts from vector form to cell array 
form, essentially does the reverse of polysplit
returns the NaN ended segments of vectors latcells and loncells 
one vector per cell of new cell arrays lat and lon

polyjoin:
converts line or polygon parts from cell array format to column vector format.
in cell array format each cell defines a seperate polygon or line segment.
returns two column vectors containing the polygons from the inputted cell
arrays. 

I have attached my implementations of these two functions for discussion,
thanks

Alex Provan
