# Erector Page base class.
#
# Allows for accumulation of script and style tags (see example below) with either
# external or inline content. External references are 'uniq'd, so it's a good idea to declare
# a js script in all widgets that use it, so you don't accidentally lose the script if you remove 
# the one widget that happened to declare it.
#
# At minimum, child classes must override #body_content. You can also get a "quick and dirty"
# page by passing a block to Page.new but that doesn't really buy you much.

# Ruby implementation of Smalltalk's "if" construction. See also
# http://pozorvlak.livejournal.com/94558.html
#
# Note that since I can't cleanly pass in more than one anonymous block to a
# method in Ruby, I have to implement it as two methods rather than
# Smalltalk's cleaner "ifTrue:ifElse:" single method. This means that in order
# to get the syntax for chaining, I lose Ruby's ability to return a value from
# "if", which is pretty cool in itself.

# How would you test this Quiz#problem method? Only two rules:
#
# 1. The tests should fail if any part of the application breaks.
#    For example: If "gets" is moved before "puts" then the tests should
#    fail since that breaks the application.
#
# 2. You cannot change the Quiz class. But you can use whatever framework
#    and tools you want for the tests. (RSpec, Cucumber, etc.)
