Jamie Kennea reports problems with extractor on Intel Mac when filtering on a region. If an indirect file was in use for the input event files it was being opened multiple times and not closed. Eventually this generated an error in the fortran open statement. Also moved the ADDFN routine from extractor.f to wstdky.f because it was only being called from WSTDKY. These fixes are v4.76 and go out with HEAsoft 6.2.
Followed up with a whole bunch of mainly cosmetic changes to eliminate most of the compiler warning messages from g95. This is v4.77 and is not part of HEAsoft 6.2.
Another iteration for 4.78 which simplifies the code for reading the file containing the names of input event files and ensures that this file is not opened again when it is already open.
