[imp-dev] unrestricted integers and reals in pdb.values

[Jurgen Vinju <Jurgen.Vinju@xxxxxx>]

Hi Imps,

My current checkout of pdb.values currently hides BigInteger and BigDecimal instead of int and double. And.. I've renamed "double" to "real"
where ever that was appropriate. 

The idea is that this simple use of the java library provides the needed level of abstraction. Later we might optimize in different implementations of IValueFactory
for faster or smaller representations.

I'm working on the implications of these changes in code that uses pdb.values, so I have not committed yet. I am planning to do that tomorrow.

Cheers,

Jurgen
