Only accepts filename 'testdatafile'

[npolizzi]

Hi, first of all, this is a really great program. Thanks!! I installed on my 2017 macbook pro (running Sierra 10.12.6) and for some reason the code only will accept input with the filename 'testdatafile'. With any other filename for the input, I get the following error:

setcover(12637,0x7fffec1be3c0) malloc: *** mach_vm_map(size=18446744072364584960) failed (error code=3)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
libc++abi.dylib: terminating with uncaught exception of type std::bad_alloc: std::bad_alloc
Abort trap: 6

Lastly, it would be very nice if this code could be put into a python module so that I can access it directly from a python list of lists (where the lists are the sets), as opposed to having to print to file, run setcover, then read in the text file output from setcover back into python.

Thanks for the great code!!

Thank you, @gandreadis! The commit has helped me. Maybe @martin-steinegger could consider merging it to master :).
