Bio::CodonUsage::IO - for reading and writing codon usage tables to file


  use Bio::CodonUsage::IO;

  ## read in a codon usage file
  my $io = Bio::CodonUsage::IO->new(-file => "in");
  my $cut = $io->next_data();

  ## write it out again
  my $out = Bio::CodonUsage::IO->new(-file => ">out");


This class provides standard IO methods for reading and writing text files of codon usage tables. These tables can initially be retrieved using Bio::DB::CUTG. At present only this format is supported for read/write.

Reading a CUTG will return a Bio::CodonUsage::Table object.
