compil with windows purely

[francois PEGORY]

dear all,
i succeed to install beancout (and fava) directly in windows.

so to do this, first you need install Visual C++  ate least vc14 http://landinghub.visualstudio.com/visual-cpp-build-tools  select windows 10 sdk
then

pip install --upgrade setuptools

then pip install beancount will  work if we make few change.
i have a problem with unistd.h
so if i put in lexer.h it compile without any problem
and add "

the only problem i don't solve is i can't install it with 
python setup.py develop i receive "wrong hash of the last lexer"
it only work if do 
pip install .
