Subject: [PATCH 3/8] Publish to NPM
Authenticate with NPM via .npmrc and publish the package version + "-[git sha]".
Remove vm and vm.min.js, they'll be built before the package is published to NPM and available on installation. When installing from git, the build step will run on npm install.

-
- // a transform stream is a readable/writable stream where you do
- // something with the data. Sometimes it's called a "filter",
- // but that's not a great name for it, since that implies a thing where
- // some bits pass through, and others are simply ignored. (That would
- // be a valid example of a transform, of course.)
- //
- // While the output is causally related to the input, it's not a
- // necessarily symmetric or synchronous transformation. For example,
- // a zlib stream might take multiple plain-text writes(), and then
- // emit a single compressed chunk some time in the future.
- //
- // Here's how this works:
- //
- // The Transform stream has all the aspects of the readable and writable
- // stream classes. When you write(chunk), that calls _write(chunk,cb)
- // internally, and returns false if there's a lot of pending writes
- // buffered up. When you call read(), that calls _read(n) until
- // there's enough pending readable data buffered up.
- //
- // In a transform stream, the written data is placed in a buffer. When
- // _read(n) is called, it transforms the queued up data, calling the
- // buffered _write cb's as it consumes chunks. If consuming a single
- // written chunk would result in multiple output chunks, then the first
- // outputted bit calls the readcb, and subsequent chunks just go into
- // the read buffer, and will cause it to emit 'readable' if necessary.
- //
- // This way, back-pressure is actually determined by the reading side,
- // since _read has to be called to start processing a new chunk. However,
- // a pathological inflate type of transform can cause excessive buffering
- // here. For example, imagine a stream where every byte of input is
- // interpreted as an integer from 0-255, and then results in that many
- // bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
- // 1kb of data being output. In this case, you could write a very small
- // amount of input, and end up with a very large amount of output. In
- // such a pathological inflating mechanism, there'd be no way to tell
- // the system to stop doing the transform. A single 4MB write could
- // cause the system to run out of memory.
- //
- // However, even in such a pathological case, only a single written chunk
- // would be consumed, and then the rest would wait (un-transformed) until
- // the results of the previous transformed chunk were consumed.

- * and here:
- * https://github.com/LLK/scratch-blocks/blob/develop/tests/
- * (for the shadow blocks created for each block).
