Extract the comments part of the .abf file.

[iampritishpatil]

the comment part is the one between .pro and IN . This change tries to extract it

Could you please explain in detail what kind of information you intend on extracting? Ideally, by providing a small-size abf file which contains that information? Also, the field name 'comment1' is not very informative. In the few files I tested your code results in h.comment1 being one single empty space.
