additional math function library available (RESEND)

[Mario Wolczko]

[I'm not sure this made it out, so I'm resending it]

On self.stanford.edu and mushroom.cs.man.ac.uk in the Self 3.0 patch
area (self.stanford.edu:/pub/Self-3.0/patches,
mushroom.cs.man.ac.uk:/pub/self/3.0/patches) are files which add
various math functions to traits number by connecting to the C math
library (names in parens are the C lib names):
	sin	cos	tan
	asin	acos	atan	atan2
	sinh	cosh	tanh
	squareRoot (sqrt)
	raisedTo: (pow)
	log	log10
See transcendental.readme for more details.
