* Support multiple ranges in the benchmark google-benchmark library allows to provide up to two ranges to the benchmark method (range_x and range_y). However, in many cases it's not sufficient. The patch introduces multi-range features, so user can easily define multiple ranges by passing a vector of integers, and access values through the method range(i). * Remove redundant API Functions State::range_x() and State::range_y() have been removed. They should be replaced by State::range(0) and State::range(1). Functions Benchmark::ArgPair() and Benchmark::RangePair() have been removed. They should be replaced by Benchmark::Args() and Benchmark::Ranges().
