====== Get Elevation Graph Tops And Bases ======

===== Description =====

This functor retrieves the list of patches that correspond to local maxima and minima from the elevation patch graph.

===== Inputs =====

^ Name  ^ Type  ^ Description  ^
| Elevation Graph | [[Elevation Graph Type]]  | Graph of elevation patches created from the neighborhood relationships and their properties.  |

===== Optional Inputs =====

None.

===== Output =====

^ Name  ^ Type  ^ Description  ^
| Tops  | [[Table Type]]  | List of properties of elevation patches corresponding to local maxima. The table has format "id*:real, elevation:real, area:real, slope:real".  |
| Bases  | [[Table Type]]  | List of properties of elevation patches corresponding to local minima. The table has format "id*:real, elevation:real, area:real, slope:real".  |
