String extensions

[nardele salomon]

I started project to create a library of  basic functions (or 'helpers' as you wish) .

The start with ds_string.   want to  contribute:  was already made ​​available at rubygem.org

Has two basic functions:

"A".times(3) => "AAA" (like "A" * 3 )

"A".times(3) do |s| "#{s}-" end  => "A-A-A-"

"1".to_b  => true

"yes".to_b => true

=)
