Add a Slice in a router namespace
@param slice_module<String, Symbol, Module> A Slice module to mount. @param options<Hash, String> Optional hash, set :path if you want to override what appears on the url.
@yield A new Behavior instance is yielded in the block for nested routes - runs before the slice routes are setup. @yieldparam ns<Behavior> The namespace behavior object.
@return <Behaviour> The current router context.
@note If a slice has no routes at all, the activate hook won‘t be executed.
@note Normally you should specify the slice_module using a String or Symbol
this ensures that your module can be removed from the router at runtime.

Add all known slices to the router
By combining this with Merb::Slices.activate_by_file and Merb::Slices.deactivate one can enable/disable slices at runtime, without restarting your app.
@param config<Hash>
Optional hash, mapping slice module names to their settings; set :path (or use a string) if you want to override what appears on the url.
@yield A new Behavior instance is yielded in the block for nested routes. @yieldparam ns<Behavior> The namespace behavior object.
@example all_slices(‘BlogSlice’ => ‘blog’, ‘ForumSlice’ => { :path => ‘forum’ })
@note The block is yielded for each slice individually.
# File merb-slices/lib/merb-slices/router_ext.rb, line 18
18: def all_slices(config = {}, &block)
19: Merb::Slices.slice_names.each { |module_name| add_slice(module_name, config[module_name] || {}, &block) }
20: end
Insert a slice directly into the current router context.
This will still setup a namespace, but doesn‘t set a path prefix. Only for special cases.
