Test for (and implement) universal coercion (for duration arguments)

Every function in the public API to accept a duration argument should allow for reduced (n, d) style input.

All that is required to do this is a ...

  duration = abjad.Duration(duration)

... line at the head of the function.

The real trick here is writing some sort of script that can iterate all 1000 public functions and introspect the signatures of each for the presence of a 'duration' argument.

Parameterized tests can now be written for this.

Still valid in May 2017.
