* These objects are the currency accepted by SJCL's crypto functions.
* </p>
*
* <p>
* Most of our crypto primitives operate on arrays of 4-byte words internally,
* but many of them can take arguments that are not a multiple of 4 bytes.
* This library encodes arrays of bits (whose size need not be a multiple of 8
* bits) as arrays of 32-bit words. The bits are packed, big-endian, into an
* array of words, 32 bits at a time. Since the words are double-precision
* floating point numbers, they fit some extra data. We use this (in a private,
* possibly-changing manner) to encode the number of bits actually present
* in the last word of the array.
* </p>
*
* <p>
* Because bitwise ops clear this out-of-band data, these arrays can be passed
* to ciphers like AES which want arrays of words.
* </p>
