Create a configurable calculation and a transparent counting wrapper.
Prototype: make_multiplier(factor) returns a callable accepting one number and returning that number times factor. Separate calls retain independent factors.
Final: count_calls(function) returns a wrapper that accepts positional and keyword arguments, returns the original result, and propagates original exceptions. Expose integer attribute wrapper.calls, initially 0. Increment it before every invocation, including calls that raise. Preserve the wrapped function's __name__, __doc__, and __wrapped__ using functools.wraps. Each wrapper has its own counter. Example: after wrapping abs, calls with -2 and -3 return 2 and 3, and .calls is 2. Thread safety is outside this exercise.
Complete the starter code, then run the checks.
