erf(Infinity) should return 1, not NaN

Likewise, erf(-Infinity) should be -1. This is true for any really large
|x|...say, |x| > 2^53.

Fix erf(bignumber) -> bignumber to return proper value
...
Note: The precision for the bignumber returned may not be accurate, as
the `erf()` approximation only guarantees precision to a certain degree.

Create spec for erf() and include test data

Values in `erf.values.json` come from python's `math.erf()`. Actual
values should be within 5e-16 of the expected values.
Test against real number, matrix, array, bignumber, boolean, and
null values.
