When editing a child record, the map should display each of the parent records.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a survey with a census method that contains a child census method. 
The issue will be highlighted best if the parent census method has a polygon 
geometry and the child censusmethod has a point or line geometry.
2. Create a record for the parent census method
3. Create a record as a child of the previous record.

What is the expected output? What do you see instead?
This is more of a feature than a bug but the issue is that unless you know 
exactly where the parent polygon was created, it can be hard to create a child 
record geometry within the bounds of the parent polygon because it is not shown 
on the map.
