Title: Add support for combining brushed axes with OR.

Up to know, brushed axes where combined using AND, meaning: a line must go
through all brushes to be *inside* the selection.

This commit adds the possibility to do OR combining, meaning: a line must
go through at least one brush to be *inside* the selection.

Usage: d3.parcoords(div).brushPredicate("OR")
