@Beta
public static Map<Class<?>,Method> getChildrenClassToNonnullMethod(Class<?> type)

  - getAugmentations
```
public static Map<Class<? extends Augmentation<?>>,Augmentation<?>> getAugmentations(Augmentable<?> input)
```
    Extracts augmentation from Binding DTO field using reflection.
    
    Parameters:
    
    input - Instance of DataObject which is augmentable and may contain augmentation
    
    Returns:
    
    Map of augmentations if read was successful, otherwise empty map.
  - isSubstitutionFor
```
public static boolean isSubstitutionFor(Class potential,
                                        Class target)
```
    Determines if two augmentation classes or case classes represents same data.
    Two augmentations or cases could be substituted only if and if:
    - Both implements same interfaces
    - Both have same children
    - If augmentations: Both have same augmentation target class. Target class was generated for data node in grouping.
    - If cases: Both are from same choice. Choice class was generated for data node in grouping.
    Explanation: Binding Specification reuses classes generated for groupings as part of normal data tree, this classes from grouping could be used at various locations and user may not be aware of it and may use incorrect case or augmentation in particular subtree (via copy constructors, etc).
    Parameters:
    
    potential - Class which is potential substitution
    
    target - Class which should be used at particular subtree
    
    Returns:
    
    true if and only if classes represents same data.
