+ *
+ * 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.
+ *
+ *
+ *
+ * Because bitwise ops clear this out-of-band data, these arrays can be passed
+ * to ciphers like AES which want arrays of words.
