Swap position of compare and node size args. See rationale added at beginning of map.hpp and set.hpp. Remove reserve argument from index set ctors and opens, in preparation for adding configuration hint flags.
Add optimization hints. Add hint based recommendations, Add handy constants. Rename open_flags() to user_flags() to better indicate functionality. Add some test cases. Revise bt_time to expose the new hints, and to improve clarity of option switch names. Revise the bt_time VC++10 project to exercise a number of the option switches.
Initial commit.
