Only applicable to nested data structures. If you want to change the parent structure, but also one of its
children, you can fill out this data strucutre. It is also <code>Mapping</code>, but its <code>FromPath</code>
will be the parent's <code>FromPath</code> plus the <code>FromPath</code> from this structure.
</p>
<p>
For the children part, suppose you have the structure:
</p>
<p>
<code>{ "FromPath": "OuterStructure", "ToKey": "OuterStructure", "ToType": "Struct", "Dropped": false, "Chidlren": [{ "FromPath": "inner", "ToKey": "inner", "ToType": "Double", "Dropped": false, }] }</code>
</p>
<p>
You can specify a <code>Mapping</code> that looks like:
</p>
<p>
<code>{ "FromPath": "OuterStructure", "ToKey": "OuterStructure", "ToType": "Struct", "Dropped": false, "Chidlren": [{ "FromPath": "inner", "ToKey": "inner", "ToType": "Double", "Dropped": false, }] }</code>
