Slice a nested hash

The attached initializer gives your hashes a #deep_slice method that lets you recursively slice their contents by a given whitelist of allowed keys and sub-keys:

{ :a => { :b => 'b', :c => 'c' } }.deep_slice(:a => :c) # => { :a => { :c => 'c' } }

makandra has been working exclusively with Ruby on Rails since 2007. Our laser focus on a single technology has made us a leader in this space.
