* Fixed doc typo
* Made min and max always return the tightest type and work with mixes of signed and unsigned
* Changed enum value names to obey lowercase convention
* Changed OrderStrategy with SwapStrategy as it's not just for ordering (e.g. see eliminate)
* Changed nthElement to topN
* Removed spurious unittest-related code from sort
* Replaced makeIndex with the more flexible partialIndex
* Commented out schwartzMakeIndex for now
* Added schwartzIsSorted
* Removed spurious test code from lowerBound, upperBound
std.contracts: added functions pointsTo()
