I have a file with a list of cities in it. The file is a daily feed and 
the cities in it change daily.

I want to create a class which reads the file and creates the variables 
with the city names.
File.open("file").each{ |x|
@"x" = 1 #I need a logic for this
end

this would give us @toronto = 1, @miami = 1, etc.

I have subclasses which would read user input and if that city variable 
has been defined already then move ahead.
it would be a simple if statement
if @toronto
...
end

I could create a hash map too but this is the easiest way to do since it 
doesnt require the  creation of any sort of a container variable.
