EditorIndexMapper

```
public class EditorIndexMapper

                    
```
The indexes in the Editable text and ComposerModel may differ if we take into account ExtraCharacterSpan that are added for lists.
These spans are used to mark extra characters that are not present in the original HTML output, mainly extra line breaks between list items.

```
    Translates the start, end indexes that come from the editableText into indexes that can be safely used in the ComposerModel.
    For this, ExtraCharacterSpan spans are used: we look for them in the editableText, then sum their lengths and subtract these lengths to the start and end original indexes.
