 * Master header for Decaf library.

 *

 * The Decaf library implements cryptographic operations on a elliptic curve

 * groups of prime order p.  It accomplishes this by using a twisted Edwards

 * curve (isogenous to Ed448-Goldilocks or Ed25519) and wiping out the cofactor.

 *

 * The formulas are all complete and have no special cases.  However, some

 * functions can fail.  For example, decoding functions can fail because not

 * every string is the encoding of a valid group element.

 *

 * The formulas contain no data-dependent branches, timing or memory accesses,

 * except for decaf_XXX_base_double_scalarmul_non_secret.
