Setup environment variables for Windows

[rdbo]

The variables in the title can be used to resolve libmem's include directory and library paths. Setting the %PATH% environment variable has proven to be useless.

This also can't really work in practice, because you may have 32 bit and 64 bit libraries on your system Also, since there are many runtimes, such as /MT, /MTd, /MDd, etc, you can't just provide a path to a single libmem.lib

[rdbo]

One possible solution is adding environment vars for libmem, such as LIBMEM_DIR, LIBMEM_INCLUDE_DIR, LIBMEM_LIB_DIR And for compiling, you could link against %LIBMEM_LIB_DIR%\libmem-4.4.0-x86_64-windows-msvc\lib\libmem.lib

NOTE: INCLUDE: adds to the compiler include directory LIB or LIBPATH: not sure yet, but I think the later one adds to the library lookup path

NOTE: Remember to set libmem-specific environment vars, and use them as lookup directories on Python bindings
