Remove support for (outdated) 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.
I also changed
- the eoQuadratic into eoQuad (as dicussed with Maarten)
- the eoBin into eoBit, with more appropriate names for the "binary"
operators (that can be unary!) as no one protested when I posted on
eodev list
eo everything that is general to any representation
es.h everything about real representation (in es dir)
ga.h everything related to bitstring representation (in ga dir)
To be continued by gp.h, and ...
This has lead to some slight modifications in test file eobin and all tutorial
examples files...
