merged special.coffee into quad.coffee
implemented ⎕DL as the first CPS function
moved ≢ to prelude
moved ⍪ to prelude
moved dyadic ⊃ (Pick) to prelude
compiling apl.js without coffee's --bare option
relaxed comparison tolerance in tests a little

one of the tests fails in browsers by a narrow margin
removed unused method APLArray.get()
sped up compiler a little

Normally i would use
    node[offset...].each (child) -> etc
for looping, but this:
    for i in [offset...node.length] by 1 then child = node[i]; etc
turns out to be way more efficient
meta info assigned directly to function objects

previously it was in a separate object: f.aplMetaInfo = {}
refactored error handling
avoided usages of eval, minifiers don't like them
removed some syntactic noise from compiler.coffee
added "npm install" to build script
switched to vanviegen's branch of CoffeeScript
Merge remote-tracking branch 'origin/master' into gh-pages
built demo
