expint.m: Overhaul function.
Better accuracy and faster performance.
Improved documentation and added %!tests.
* scripts/specfun/expint.m: Improved accuracy of calculations by adjusting
quad() tolerance options. Speeded up performance by breaking out of series
summation as soon as possible. Used persistent variables to avoid
re-calculating expensive intermediate values. Added %!tests verified against
arbitrary precision Mathematica calculations.
