Minimalist C++-only TTK example pipeline, including:
-# The computation of a persistence curve
-# The computation of a persistence diagram
-# The selection of the most persistent pairs of the diagram
-# The pre-simplification of the data according to this selection
-# The computation of the Morse-Smale complex on this simplified data
-# The storage of the output of this pipeline to disk.

This example reproduces the Figure 1 of the TTK companion paper: 
"The Topology ToolKit",
