makeGridTopology

any Spatial object, or other object for which <code>bbox</code> will work

the number of cells of the grid, x then y

cells.dim

xlim

ylim

proportional size of the buffer to add to the grid limits

buffer

cellsize

assume cell size is in kilometres and provide
  simple adjustment for earth-radius cells at the north-south centre of
  the grid

adjust2longlat

Sensible defaults are assumed, to match the extents of data to a manageable
  grid.

  Approximations for kilometres in longlat can be made using
  <code>cellsize</code> and <code>adjust2longlat</code>.

manip

Functions for accessing and manipulating spatial data for
        animal tracking.  Filter for speed and create time spent plots
        from animal track data.
