The following has been implemented:
* ImfStandardAttributes.h defines a new framesPerSecond attribute
whose value is of type Rational.
* Class Rational, defined in ImfRational.h supports implicit
conversion to double. There is no implicit conversion from
double. Explicit conversion from double is supported;
converting NTSC-like frame rates from Rational to double
and back is lossless.
* ImfFramesPerSecond.h defines the exact values of a few common
frame rates. The header also includes a function that tries
to guess exact frame rates from approximate ones. For example,
guessExactFps(29.97) returns Rational(30000,1001).
