class_docstr: A class that creates a grid of Axes. In matplotlib, the axes
  location (and size) is specified in the normalized figure
  coordinates. This may not be ideal for images that needs to be
  displayed with a given aspect ratio.  For example, displaying
  images of a same size with some fixed padding between them cannot
  be easily done in matplotlib. AxesGrid is used in such case.
docstr: get geometry of the grid. Returns a tuple of two integer,
  representing number of rows and number of columns.
docstr_tok: ["get","geometry","of","the","grid",".","Returns","a","tuple","of","two","integer",",","representing","number","of","rows","and","number","of","columns","."]
