[NTG-context] Updated My Way on math alignment

Hi, I have updated myway on using alignment. It now also explains features of matrix (similar to array of latex), cases, substack and intertext. Most of the discussion on mathalignment (similar to align and gather environments of latex) is the same as before. http://dl.contextgarden.net/myway/mathalign.pdf source http://dl.contextgarden.net/myway/mathalign.tex Taco, I am also describing how to use style=... feature of matrix that you sent a while back, hoping that it will make to the core :-) Aditya
