2008-08-20, version 3.0.1

The double datatype with scaling technique is implemented. The long double
is no longer used, thus speedup the program at least twice. 

Memory consumption is also reduced at least one half by another organization
of the partial likelihood vector.

A minor bug in GTR model was fixed, which made the intialization of model
parameters incorrect.

Version 3.0

From version 3.x IQPNNI can also be compiled as an MPI parallel program.
