#
# A mutation of "open" that lets you read/write gzip files, as well as
# regular files.
#
# (NOTE: gzip detection is based on the filename, not the contents.)
#
# It accepts a block just like open()!
#
# Example:
# zopen("test.txt") #=> #<File:test.txt>
# zopen("test.txt.gz") #=> #<Zlib::GzipReader:0xb6c79424>
# zopen("otherfile.gz", "w") #=> #<Zlib::GzipWriter:0x7fe30448>>
# zopen("test.txt.gz") { |f| f.read } # read the contents of the .gz file, then close the file handle automatically.
#
