[IMP-dev] Grid class

[Daniel Russel <>]

Here is a proposed grid class (I haven't even tried to compile it). It  
can map between real space and voxels.

The differences from the grid used in EMBed are:
- The voxel index is actually a triple if ints. This makes computing a  
point in a voxel fast without the large tables used in EMBed. I think  
this is the right choice speed wise, but we can always test (and it is  
trivial to change).
- the names are changed to be more consistent with IMP
- the voxel data is a template argument
- it is copyable
- currently there is no resize function and I don't really know what  
would be meant by it and the obvious things involve lots of moving of  
data around.
