   Format: MarkdownIn preparation for [week296](http://math.ucr.edu/home/baez/week296.html) I corrected the definition of [dagger-compact category](http://ncatlab.org/nlab/show/dagger-compact+category), since it was missing some coherence laws. The most convenient way to include these was to add a page containing Selinger's definition of [symmetric monoidal dagger-category](http://ncatlab.org/nlab/show/symmetric+monoidal+dagger-category) . This in turn forced me to add pages containing definitions of [associator](http://ncatlab.org/nlab/show/associator), [unitor](http://ncatlab.org/nlab/show/unitor), "braiding":http://ncatlab.org/nlab/show/braiding and [unitary morphism](http://ncatlab.org/nlab/show/unitary+morphism). Some of my links between these pages are afflicted by the difficulty of getting daggers to appear in names of pages. Maybe a lab elf can improve them. Hmm, html links didn't work here, so I'm trying textile.

We can use double square brackets just like the n-Lab to link to n-Lab pages now :) It might make things a little easier in the future. >In preparation for [week296](http://math.ucr.edu/home/baez/week296.html) I corrected the definition of [[dagger-compact category]], since it was missing some coherence laws.
