Source code change that represents the insert of an entity.
In addition to the involved entities described in {@link SourceCodeChange} an insert has a
- {@link SourceCodeEntity} parentEntity that describes in which entity changedEntity isinserted. Speaking of an AST, parentEntity describes the node in which changedEntity will be a child after the insert. parentEntity is taken from the left AST, i.e., old version. In case parentEntity was inserted (see {@link SourceCodeChange}), it is taken from the right AST.
