[BioC] a question about girafe

[Joern Toedling]

Hello,

note that package "girafe" also contains a function called "agiFromBam" 
which directly reads in sorted and indexed BAM files into an object of 
the AlignedGenomeIntervals class. This function also relies on 
functionalities of the Rsamtools package but should be faster and more 
memory-efficient than first using "readAligned" and then converting the 
result into an AlignedGenomeIntervals object. Please let me know if 
there are any issues with that function.

Cheers,
Joern
