ENH: reading headers and footers using loadtxt

[giochanturia]

Proposed new feature or change:

numpy.savetxt has header and footer as parameters. It would be nice to have a reverse functionality while loading the file using numpy.loadtxt.

Hey, probably it is best to add a function line numpy.loadtxt_with_comments (name can change), that with return the comments (Header and Footer are considered comments) too, so you don't lose them.

For removing header and footer while loading a file, numpy.genfromtxt can be used instead which provides handling of the comments as well. It isn't fast enough though compared to numpy.loadtxt. For using numpy.loadtxt, skipping header is as straightforward as setting the argument skiprows as the number of lines in header. Handling footers in numpy.loadtxt could be a challenge though.
