Remove support for (outdated) <strstream>, require <sstream>.
Require uint32_t for now, defined in stdint.h according to C99.
Some general cleanup and more documentation.
Apart from big changes in the src/ga dir, and the addition of the src/do dir
it also generated a few changes here and there, e.g. some include file still
missing. Also removed some warning from some test files.
To be able to use the primitive std::generate function, added a
set of wrappers in eoSTLFunctor.h that have the copy semantics most
STL functions expect (namely pass-by-value rather then pass-by-reference).
Updated test/Makefile.am to also test t-eoRandom
