Implement C++14 std::make_reverse_iterator
[FOLD] Factor out common code, eliminate redundancies
[FOLD] base_uint::ToString -> to_string(base_uint const&)
[FOLD] (Optional) Remove base_uint::GetHex
[FOLD] Address comments; slighty improve STAmount::getText
[FOLD] Eliminate unnecessary copying in STAmount::getText
[FOLD] Don't allocate, take advantage of short-string optimizations
[FOLD] (Optional) use std algorithms not hand-rolled loops
[FOLD] Use std::make_reverse_iterator
