One problem with the octree data is that it currently only supports single-byte scalar data, not 32-bit float.

To fix it, one would have to do a fair amount of modification in the code.

The code typdefs unsigned chars to 'ST' for easy editing so to support both 8 and 32 bit scalars I must change the code which uses this typedef to use templates instead.

After examining the code I believe this would involve:

- Converting any existing objects which contain ST variables into template equivalents - Moving any individual ST variables into a single template object - Converting any existing functions which take/return ST variables into template equivalents - Obtaining the type of the data in the octree file being read (using the C++ typeid operator) and using this to instantiate objects and functions of the appropriate type

I'm already part way through this but would appreciate if you could confirm if you agree with this approach. It does require a lot of tricky code modification so it would be reassuring to know that I'm on the right track ;)

Thanks
