[sawa (Tsuyoshi Sawada)]

In IO class, there are pairs of a class method and an instance method with related function:

• IO.read and IO#read
• IO.write and IO#write
• IO.foreach and IO#each (or its alias IO#each_line)

For consistency, please make IO.each an alias for IO.foreach.

The same thing can be said for CSV.each.

• Subject changed from IO.each (and perhaps CSV.each) to `IO.each` and `CSV.each`
