Make mrcfile.validate silent

[cdienem]

Hi.

I have a small suggestion for improvement. Would it be possible to make the printed output of mrcfile.validate() optional in case I am just interested in a bolean return value?

Best and thanks,
Chris

That should be easy enough so I will certainly consider adding it next time I make an mrcfile release.

In the meantime, Python's contextlib makes it quite easy to capture the print output if you need to:

import contextlib
import io
import mrcfile
with contextlib.redirect_stdout(io.StringIO()):
    result = mrcfile.validate('file.mrc')

If the files are badly invalid you might also get warnings on stderr, which you can suppress similarly with contextlib.redirect_stderr or Python's standard warning controls.
