two bugs in PATHLINE

[derbuur]

Hi, I found two bugs in PATHLINE.

1. In the function PATHLINE:GetPointFromIndex(n) it must be self.points[n] instead of self.point[n]

   function PATHLINE:GetPointFromIndex(n)
   
   local N=self:GetNumberOfPoints()
   
   n=n or 1
   
   local point=nil --#PATHLINE.Point
   
   if n>=1 and n<=N then
   point=self.points[n] -- must be points not point
   else
   self:E(self.lid..string.format("ERROR: No point in pathline for N=%s", tostring(n)))
   end
   
   return point
   end

2. in the function PATHLINE:GetCoordinats() is the table.insert misssing.

   function PATHLINE:GetCoordinats()
   
   local vecs={}
   
   for _,_point in pairs(self.points) do
   local point=_point --#PATHLINE.Point
   local coord=COORDINATE:NewFromVec3(point.vec3)
   table.insert(vecs, coord) -- this line was missing
   end
   
   return vecs
   end
