f6a8878aa2 Varint class 
...will be useful in transactions. Note that we already have a primitive
understanding of Varints in the BufferReader and BufferWriter classes. However,
the new Varint class is a varint object which actually depends on BufferReader
and BufferWriter for reading and writing varints. This class is for keeping
track of the raw buffer that is read in from a buffer.

3c668c9cf0 readVarInt -> readVarIntNum 
"varInt" refers to the varInt object, which is not actually implemented yet.
This function should therefore really be called readVarIntNum.

8e959426e2 support reading varInt nums up to js precision 
Javascript only supports 64 bit floating points, which have uint precision up
to Math.pow(2, 53). We now support reading variable sized numbers up to that
size. If the number is bigger than that, then we need to use BN.

79d79012d4 fix bug where you can't use isForMe without payloadKeypair 
It should be possible to check to see if a message isForMe with only the
scanKeypair, and not the payloadKeypair. There was a bug where only the
scanKeypair was being used to produce the receiveKeypair, but this was a
mistake. Both the scanPubkey and payloadPubkey should be necessary to produce
the receivePubkey, and both the scanPrivkey and payloadPrivkey should be
necessary to produce the receivePrivkey. If an online computer has only the
public keys of both (and the scanPrivkey), then that is good enough to check
for isForMe.

5a86a1a5c6 StealthMessage

3b2b725070 Script().fromString(str) 
...the format of fromString and toString are deliberately not compatible with
bitcoind. The format here is supposed to be both human-readable, and
byte-for-byte isomorphic to the binary representation. In the future we will
need to add support for bitcoind-like strings, both for the test data (e.g.,
script_invalid.json) or for the bitcoind console style.

378dc923ef preserve claimed length and op code 
When parsing OP_PUSHDATAX commands, the the length of data might not require
the size integer of OP_PUSHDATAX. For instance, you might write 1 byte, and yet
use OP_PUSHDATA4. We need to record which OP_PUSHDATAX was used so that when we
write the buffer back out, we can write the same one. Also, the claimed length
may be different. For instance, we may OP_PUSHDATA of length 100 to the stack,
but there may only be 50 bytes left in the script. In that case, buf.length and
chunk.len will be different. I'm not sure if that would be considered a valid
script, but in any case, for script analysis, we need both values.
