Get 64-bit builds working. Update timings to reflect 64-bit build.
Use detail::reverse_value() to implement reverse_value() for float and double, thus eliminating type-punning warning from gcc.
Rename the endian typedefs. Rationale: Subjective - during three months working on the B-tree library, the *un_t names were a constant source of irritation. Objective - the new scheme, which reverts the *un_t names to having no alignment decoration, provides consistent *_align* decoration for both FP and integer types. Also, the library now provides conversion functions which may reduce use of aligned endian types.
Add the build .bat files as a maintenance aid.
