    added (here) brief statement of Shum’s theorem with pointer to:

    • Mei Chee Shum, Tortile tensor categories, Journal of Pure and Applied Algebra 93 1 (1994) 57-110 [10.1016/0022-4049(92)00039-T]

    Have touched the wording of what is now the second paragraph of the Idea-section, being more explicit/correct about the relation between tangles and knots/links.

    Also added, below that, a sentence about braids as another special case of tangles.
