ImportH5ObjectPathsAction will allocate memory for every data set during 'apply(...)' function

The issue is on line 44 of ImportH5ObjectPathsAction.cpp. During execute() we are first looking at the entire data structure to figure out if it is valid I suppose. The issue is that Mode is set to "execute" which means each and every single array is going to be allocated temporarily until that function is completed.

Do we need to send in the list of paths that are being imported perhaps?
