Cmiss Region
- FE region
  Provides a scope within which fields, nodes and elements are unique. Holds lists of many of the data structures that can be shared between nodes and between elements Manages change logs for contained nodes and elements and callbacks for external objects interested in those changes.
  - FE field
    - Name
    - Type
    - Number of components
    - Coordinate system
    - Value type
    - Values storage
      Fields can store their own values (constant and indexed fields)
  - Nodes
    - Node field info
      - Node field
        
        FE field
        
        FE time sequence
        
        versions/derivatives
      - FE region
    - Value storage
  - Element
    - Identifier
    - Element field info
      - Element field
        
        FE field
        
        Basis
        
        Type
        
        Blending matrix
        
        Basis function pointers
        
        Basis function arguments
        
        Node to element map
        
        Element field values
        These are a caching mechanism where the nodal values required to evaluate the basis functions on this element are stored to speed up multiple evaluations.
      - FE region
    - Element node scale field info
      - Nodes
      - Scale factors
      - Values storage
        Used for grid points
    - Element shape
      - dimension
      - type
        A definition of topology
      - faces
      - face normals
      - face to element matrix
        A matrix that converts xi coordinates in a face element to the element
    - Parent list
    - Faces
