Parsing Cufflinks Gtf file/data, in an ActiveRecord style

gistfile1.rb

g=Bio::Ngs::Cufflinks::Gtf.new "./spec/fixture/transcripts.gtf"
g.set_lazy
a=g.multi_exon.coverage_gt(3).length_gt(200)
#not yet parsed until you iterate of the transcripts
a.multi_exons.each_transcript {|t| puts t; break}

#accessing to an exon using the indexin:
g.read_transcript(10) #return a string of the block
g.get_tranascript(10) #return an object transcript.

also g[] works.
