Minor change of the file sweeps.h

Minor change of the file sweeps.h. Now if the number of row of sweep parameters in the input file is less than nsweep, the last row will repeat.

Hi Mingpu, this is a nice idea. One question is, this seems to rely on a certain behavior of the line
table.file() >> maxm_[i] >> ...
namely that it will set maxm_[i] to zero (or leave it as zero) if there is no more input. Is this relying on a particular guaranteed behavior of the >> operator for input streams? What if someone leaves a space between the last line in the table and the closing brace (closing } )? I just want to better understand if the condition we are relying on here is robust. Thanks!

Hi Miles, thanks. I think ifstream ignores white spaces. So if there are white spaces at the end of the file, the value of maxm_[i] will be the default value when it is declared, which is 0 for std::vector.

Thanks Mingpu - I hope it doesn't lead to any surprising behavior but it is definitely an improvement to the current behavior!
