Parslet::Atoms::Base#parse_with_debug

Packages the common idiom
   
   begin
     tree = parser.parse('something')
   rescue Parslet::ParseFailed => error
     puts parser.cause.ascii_tree
   end

into a convenient method.

Usage:
  
  require 'parslet'
  require 'parslet/convenience'
  
  class FooParser < Parslet::Parser
    rule(:foo) { str('foo') }
    root(:foo)
  end
  
  FooParser.new.parse_with_debug('bar')
