Use bxxx() method names consistently, rather than mixing bxxx() and fxxx()
in code and test files. The fxxx() methods for Math::BigFloat objects are
still available through autoloading. However, we leave the fround() method
in Math::BigInt, as it seems to provide some kind of compatibility with
Math::BigFloat.Correct author information in the README file.
Remove INSTALL file, which by accident wasn't removed in v1.999707.
Use present tense, not past tense, in CHANGES file.
Add '#!perl' to Makefile.PL for correct syntax highlighting in editors
supporting this.Use Math::Complex::Inf() in testfiles also (for generating Perl scalar
infinity) since it is more portable.
