# This is pretty much just a macro for creating a class that allows
# using a block to initialize stuff and to define getters and setters
# really quickly.

# creates the attributes class variable and creates each attribute's accessor methods

# read method for attributes class variable

# allows for any class that includes this to use a block to initialize
# variables instead of assigning each one seperately
#
# Example:
#
# instead of...
#
# s = Status.new
# s.foo = 'thing'
# s.bar = 'another thing'
#
# you can ...
#
# Status.new do |s|
# s.foo = 'thing'
# s.bar = 'another thing'
# end
