Add optional rounding mode parameter to `toExponential`, `toFixed` and `toPrecision`. Add a strict mode to disallow imprecise number/Big conversions when `Big.strict = true`. Add `toNumber` method. Add `prec` method to round a Big to a specified number of significant digits. Add version selector to API documentation. Change `toJSON` to return exponential format. Remove *big.min.js*. Remove `Big.version`. Rename *doc* folder to *docs* to use it as the Github publishing source. Add legacy API documentation to *docs*. Add *README* to *perf* directory. Refactor test suite, and add `toNumber` and `prec` tests. Update *README*.
