Compile-time creation of Uint (#53) * Start on allowing compile-time stint. Works for Uint256 * remove and reorder initUintImpl, zero and one procs * Fix assignation of uint64 to 2xuint32, remove unsafeConv and use const for base/radix * assign_least_significant_words shouldn't implicitly capture result * Simplify least significant words macros 2018-06-16 16:54:40 +00:00			`import ./datatypes, ./as_words, typetraits`
