Support for square roots #24

As requested in the Beta 3 spec, we need to support more advanced calculations such as sqrts.

Most likely wontfix, right? Since BigDecimal doesn't support this operation (and we're using BigDecimal for precision) ...?

Right. Maybe it could be implemented as a low-precision-only operation, but I feel like it has limited functionality at this point. Could be added in a future branch (esp. if we write a custom arbitrary-precision implementation).
