"""
This function looks for the closest node in the mesh to the center point of the foundation elements. The center is
determined as the average between minimum and maximum coordinate in x-, y- and z-direction. All nodes are checked
with the same z-coordinate as the average.
.. warning:: Function may not find correct node if different levels are present. In that case node 0 is set.
Input:
- project (obj): VIIA project object containing collections of fem objects and project variables.
Output:
- The base node is updated or set in project.base_point.
