Lightroom/Camera Raw: Targeted Contrast Enhancement

The idea is to bring about tonal separation in specified regions, primarily for local application (e.g. adjustment brush and graduated filter).

For example, one could specify:
- Darkest tone to be affected.
- Lightest tone to be affected.
- Mid-tone (contrast 'S' curve split point).

This way one could bring out shadow detail without affecting light tones that get "caught in the net".

Likewise, one could bring out highlight detail without affecting dark tones that get "caught in the net".

This is essentially a manual version of Mark Sirota's adaptive local contrast enhancement idea, which solves some of the problems raised by Lee Jay (and would be much easier to implement). This idea is basically the same as TK's split-point controlled contrast tool, but with dark/light tonal constraints.

Summary:
========
A new local tool one can use to separate tones in a specified range without affecting tones outside the range.
