20040712 [CMcC]: I've written a [cost]-like tree editing language.  More details will follow, but I just had to grab this great pun name.

I've put up some docs and a working version of TreeCL here: http://sharedtech.dyndns.org/~colin/treecl/docs/ - [CMcC] 20040813

'''Some Examples''' from the included doc.tcl

    Costq nh -tree homepage
    puts "TEXT: [nh query tree content]"
    puts "A: [nh query tree withtag a attval href]"
    puts "A2: [nh query tree hasatt href attval href]"
    puts "SIZE: [homepage size]"
