New function psi to compute the digamma function.
* libinterp/corefcn/psi.cc: file for the new function file (implementation
is actually in lo-specfun.cc).
* liboctave/numeric/lo-specfun.cc, liboctave/numeric/lo-specfun.h: added
implementation of the digamma (psi )function. Partly based on diGamma()
from XLiFE++ 1.1 (file gammaFunctions.cpp which was previously melina++)
which is under GPL 3 or later and why D. Martin is also added to copyright.
* doc/interpreter/arith.txi: add function entry to the manual.
* libinterp/corefcn/module.mk: add file to the build system.
* NEWS: note new function.
