Array of lines passed to HL7::Message.new causes children segments to break

[untoldone]

Currently if you follow the examples of how to parse a file such as:

lines = File.readlines('<somefile>')

msg = HL7::Message.new(lines)

My current work around is to pass a string such as HL7::Message.new(File.read('<somefile>'))

This in combination with #3 made it pretty hard to get started with children.
