Check if a file system directory exists and has the correct access. This
 can be very useful to check if the application relies on a shared file sytem
 being mounted. The <tt>:path</tt> options must be supplied to the initializer. You
 may also supply an <tt>:permission</tt> option with the values <tt>:read</tt>, <tt>:write</tt>, or
 <tt>[:read, :write]</tt> to check the permission on the directory as well.

 === Example

   IsItWorking::Handler.new do |h|
     h.check :directory, :path => "/var/shared/myapp", :permission => [:read, :write]
   end
Check if a file system directory exists and has the correct access . This can be very useful to check if the application relies on a shared file sytem being mounted . The <tt > : path< / tt > options must be supplied to the initializer . You may also supply an <tt > : permission< / tt > option with the values <tt > : read< / tt > <tt > : write< / tt > or <tt > [ : read : write ] < / tt > to check the permission on the directory as well .
