...i.e., bignums, numbers, and strings. Also, ensure that if you try to
multiply a buffer, it should be exactly 32 bytes. Eventually this "multiply"
function will be replaced with a more conventional "mul" function, but not yet.
...no longer relies on Manuel's repo hostig a version of "bignum" that actually
contained bignumber.js. This moves bignumber.js internally and removes bignum
from the browser build process. Also adds a bitcore.Bignum that links to the
right thing. In node, browser.Bignum is require('bignum'). And in the browser,
bitcore.Bignum is is now Bignumber.js (same as before ... except bignumber.js
is now inside bitcore).
The addUncompressed function is for node-only, and is a temporary workaround
until we expose a better crypto interface in both node and the browser. I wrote
tests for this function that were node-only, but were broken in the browser. I
also wrote tests for the Point class that should have worked in both node and
the browser, and did, but I was using the wrong module such that it worked only
in node. This update makes the tests work in the browser by using the correct
module.
