*Description*
-------------
New spreadsheet functions implemented:

SEC computes the secant of an angle specified in radians, SEC(x)=1/COS(x)

CSC computes the cosecant of an angle specified in radians,
CSC(x)=1/SIN(x)

SECH computes the hyperbolic secant of a hyperbolic angle specified in
radians, SECH(x)=1/COSH(x)

CSCH computes the hyperbolic cosecant of a hyperbolic angle specified
in radians, CSCH(x)=1/SINH(x)

The functions are defined in the ODF 1.2 OpenFormula standard draft
available at
http://docs.oasis-open.org/office/v1.2/csprd03/OpenDocument-v1.2-csprd03-part2.odt

Export to MS-Excel is realized as the equivalent (1/COS(x)),
(1/SIN(x)), (1/COSH(x)) and (1/SINH(x)) calls.
