add exterior trigonometric functions

Browse Source 
Added the following new trigonometric functions:

    exsec(x [,eps])		exterior trigonometric secant
    aexsec(x [,eps])		inverse exterior trigonometric secant
    excsc(x [,eps])		exterior trigonometric cosecant
    aexcsc(x [,eps])		inverse exterior trigonometric cosecant

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

Added to test 34dd, some if the missing inverse trigonometric tests.
