fastio

fast input/output for competitive programming compatible with c++11

BUFSIZE must be at least 32 (but default is recommended)
Printer flushes automatically only when it is destroyed, so on interactive tasks you should automatically call .flush()
if you #define FAST_FIFSS, Scanner will be faster, but harder to use interactively.
If an unsupported type is passed, the compiler will probabilly complain of it having no .begin() method
only 64bit floating points are supported (calls with float and long double, internally will use double)
integer printing and floating points are from here
integer parsing is (partially) from here
To use on windows you can #define WINDOWS, but it won't be nice to use interactively
