"Represents an executable image section.

SBSection supports iteration through its subsection, represented as SBSection
as well.  For example,

    for sec in exe_module:
        if sec.GetName() == '__TEXT':
            print sec
            break
    print INDENT + 'Number of subsections: %d' % sec.GetNumSubSections()
    for subsec in sec:
        print INDENT + repr(subsec)

produces:

[0x0000000100000000-0x0000000100002000) a.out.__TEXT
    Number of subsections: 6
    [0x0000000100001780-0x0000000100001d5c) a.out.__TEXT.__text
    [0x0000000100001d5c-0x0000000100001da4) a.out.__TEXT.__stubs
    [0x0000000100001da4-0x0000000100001e2c) a.out.__TEXT.__stub_helper
    [0x0000000100001e2c-0x0000000100001f10) a.out.__TEXT.__cstring
