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

===== Description =====
This functor retrieves the relationship of patches that correspond to local maxima and minima of the elevation patch graph.

===== Inputs =====
^ Name  ^ Type  ^ Description  ^
| Elevation Graph | [[Elevation Graph Type]]  | Elevation patch graph created from neighborhood relationships and their properties.  |

===== Optional Inputs =====
None.

===== Output =====
^ Name  ^ Type  ^ Description  ^
| Tops  | [[Table Type]]  | Property relationships of elevation patches corresponding to local maxima. The table has the format "Top_Id*:real, Top_Elevation:real, Top_Area:real, Top_Slope:real".  |
| Bases  | [[Table Type]]  | Property relationships of elevation patches corresponding to local minima. The table has the format "Base_Id*:real, Base_Elevation:real, Base_Area:real, Base_Combined_Area:real, Base_Slope:real".  |
