Fixed SEE ALSO typo in help randperm.

Added the following new trigonometric functions:

    haversin(x [,eps])		half versed trigonometric sine
    hacoversin(x [,eps])	half coversed trigonometric sine
    havercos(x [,eps])		half versed trigonometric cosine
    hacovercos(x [,eps])	half coversed trigonometric cosine
    ahaversin(x [,eps])		inverse half versed trigonometric sine
    ahacoversin(x [,eps])	inverse half coversed trigonometric sine
    ahavercos(x [,eps])		inverse half versed trigonometric cosine
    ahacovercos(x [,eps])	inverse half coversed trigonometric cosine

Fixed calc regression test 42dd to set the display value back to 20.

Added test 95dd and test9500.trigeq.cal to the calc regression test
suite to perform extensive test of trigonometric functions.

Fix and improve recently comments and variable names added new
