simplified lazy.dom.js -- just moved into one file
added lazy.node.js for streams (see #13)
cleaned up a bunch of compiler warnings (see #7)
added lines method to StreamedSequence (see #13)

has a bug right now (I think), but I'll fix it later
pass index into map and filter (see #9)
added helper for checking index passed in (see #9)
phew! pass index in concat and flatten (see #9)
OK, passing index in several more methods (see #9)

shuffle, sortBy, without, union, intersection
pass index with uniq and zip (see #9)
pass index to reduce and reduceRight (closes #9)

...at least I THINK that's all of 'em
