SBBreakpoint supports breakpoint location iteration, for example,
for bl in breakpoint:
print('breakpoint location load addr: %s' % hex(bl.GetLoadAddress()))
print('breakpoint location condition: %s' % hex(bl.GetCondition()))
and rich comparison methods which allow the API program to use,
if aBreakpoint == bBreakpoint:
...
to compare two breakpoints for equality."
