Subject: [QUIZ] Mexican Blanket (#127) Problem

Hey all,
	I was attempting Mexican Blanket today, and found it to be more of a  
brain teaser (for me) than a coding problem.

Which doesn't mean there were no coding problems.

I keep getting an error for the Integer#times method. I think I'm  
using it right, but could someone help me correct it please?

Also, do I have my shebang setup correctly to type ./ 
mexican_blanket.rb ETC and have it run? Because I can never seem to  
get it to work.

mexican_blanket.rb:21:in `weave': undefined method `times' for

       end
     end
     @mainp = (@mainp + (@PL - 1)) % @PL
     @offp = @offp.next % @PL
   end
end

colors = ARGV[0]
length = ARGV[1]
width = ARGV[2]
pattern_length = ARGV[3]
mexico = Blanket.new(colors, length, width, pattern_length)    #THIS  
IS LINE 49
#end

I did my version of it as a top-down pattern as opposed to a diagonal  
pattern.
