Incorrect results from calling read_digital_signal when opening more than one file

Calling read_digital_signal from the first EdfReader instance is alright. However, if calling it from the following instances, it will return incorrect results. After looking at the _pyedflib.pyx, self.handle causes the problem. It has never been assigned to any value but is used in read_digital_signal. If I added

def check_open_ok(self, result):
if result == 0:
self.handle = self.hdr.handle <---- add this line
return True
else:
raise IOError, open_errors[self.hdr.filetype]

, everything seems to work correctly. I don't know why the code still needs self.handle. If removing "cdef int handle" and change self.handle to self.hdr.handle, I think _pyedflib.pyx should work as expected. Haven't tested though.

Thank you, i changed the source code.
