Detailed Description

Operator to project base functions from parent entity to child.

This operator project/collect base functions, field data (i.e. indices, field values of dofs, etc.), from parent element, into child. Operator can be called as a hierarchy to get access to information on lower refinement levels.

Examples: free_surface.cpp, and hanging_node_approx.cpp.
