-- Convert a comma and semicolon separated numbers into geojson coordinate arrays
-- Each geotype expects a certain array depth:
-- Point - [ lon, lat ] All other types use point as the basic type
-- MultiPoint - array of points: [ point, ... ]
-- LineString - array of 2 or more points: [ point, point, ... ]
-- MultiLineString - array of LineStrings: [ [ point, point, ... ], ... ]
-- Polygon - [ [ point, point, point, point, ... ], ... ]
-- each LinearRing is an array of 4 or more points, where first and last must be the same
-- first LinearRing is the exterior ring, subsequent rings are holes in it
-- MultiPolygon - array of Polygons: [ [ [ point, point, point, point, ... ], ... ], ... ]
--
-- For example, for the LineString, data "p1;p2;p3" would be converted to [p1,p2,p3] (each "p" is a [lon,lat] value)
-- LineString has the depth of "1" -- array of points (each point being a two value array)
-- For Polygon, the same sequence "p1;p2;p3" would be converted to [[p1,p2,p3]]
-- Which is an array of array of points. But sometimes we need to specify two subarrays of points:
-- [[p1,p2],[p3]] (last point is in a separate array), and we do it with "p1;p2;;p3"
-- Similarly, for MultiPolygon, "p1;p2;;;p3" would generate [[[p1,p2]],[[p3]]]
