Description: Implementation of lazy lists for ruby
Long Description: This class implements lazy lists (or streams) for Ruby. Such lists avoid the computation of values which arent needed for some computation. So its possible to define infinite lists with a limited amount of memory. A value that hasnt been used yet is calculated on the fly and saved into the list. A value which is used for a second time is computed only once and just read out of memory for the second usage.
