Merge fork with master is out of order.

Dear Bitbucket,

Since the appearance of the novel interface to manage my repositories, it became more difficult to merge my initial repository to the forked repository.

I believe that this page is out of date.

I would like to merge my repository "spp-extended-theory" to "LIPSS-database" (and NOT the opposite). Actually, the main purpose is for me to HIDE the contents of LIPSS-database to users of spp-extended-theory, as the routines included in the second latter remain unpublished in scientific litterature.

Thanks for your assistance,

Best wishes,
Thibault Derrien
