blockify docs and nodejs-code

Blockify (see libblockify) functionality in javascript for node-js, AND documentation and internals.

This is because aindigo and I decided to implement blockify in node-js, cause i stuck in implementing a network functionality and aindigo proposed to use BitTorrent's DHT to find the blocks in the network.

note that the following documents are Obsolete, since we decided to not use sha1 use the documents in ./data2/ instead

Documents

• blocks.md
• descriptor_blocks.md

(node.js)-JavaScript Files

• dblock_hdr.js : a block-header parser and generator
• block.js : block utils (currently XOR)
• block_store_util.js : block store util
• url.js : the blockify-url-parser
• disk_kv : a KV store (for storing blocks) written in pure Javascript
