Error and Exponential Integral Functions

Using original algorithms developed at Wolfram Research, the Wolfram Language evaluates error and exponential integral functions anywhere in the complex plane, to arbitrary precisionas well as supporting series expansions with careful attention to branch cuts, and an extensive web of symbolic transformations.
