sparkline(numbers, &block)

Returns a sparkline
Example:
list = [open_issue_count, closed_issue_count] Sparkr.sparkline(list) # => "▁█"
Example with block:
Let's say you have your list of open and closed issues, but you want to format it so the open ones are red and the closed ones are green, so you can quickly see how you are doing. Let's further suppose you use a gem that adds a color method to String for ANSI coloring.
line = Sparkr.sparkline(list) do |tick, count, index| if index == 0 tick.color(:red) else tick.color(:green) end end line # => "▁█" (colored, trust me)
@param numbers [Array<String, Fixnum, Float>] the numbers to be rendered @param &block [Proc] optional, can be used to format the rendered string
@return [String]
