class PProjector: public PBulkInterface

  Pluto projector interface

  The main idea of this class is to provide a very
  simple, fast and easy-to-use analysis tool, which
  make the writing of an analysis macro unnecessary.
  It uses the Bulk interface and can be plugged into
  the reaction before or after the decay

  The syntax of the commands are based on the PBatch syntax,
  for details look into the documentation of this class.

  Commands for the batch can be added in 2 ways: Either
  with AddCommand(char * command) or
  in one step together with a histogram which will
  be filled after the command has been executed.

  Input: The input for the commands must be particles
  from the data stream in the fillowing format:
  [pid,num] where pid is the pid-string (e.g. "pi0")
  and num is the number of the particle (can be omitted if only
  one particle of this type present)

  Output: _x,_y as doubles. The latter one only for 2dim histograms.
