qd-methods.lisp: * Define FLOATP * Fix bugs in FLOAT: * (FLOAT float nil) is an error * (FLOAT float) returns the float * (FLOAT rational) returns a single-float. qd-package.lisp: o Export FLOATP, shadowing CL:FLOAT. rt-tests.lisp: o Add a few tests for FLOAT.

* Allow (exp-integral-e 1 z) to work. * psi * Handle psi(1) specially. * Do a better job with cot(%pi*z) when z is an odd multiple of 1/2 where cot is 0. * Fib bug in computing the number of terms when we try to float a complex. Just float the realpart.

For exp-integral-e, use the series for small z and the incomplete-gamma-tail for near the negative real axis. Otherwise, use the continued fraction. In incomplete-gamma-tail, we were using the continued fraction instead of the incomplete-gamma function for the region just below the negative real axis. We should use the cf except in that region.
