sim.gradient

Function returns a vector using the sine wave function \(y = depth*sin(cycles*pi*(x-1/4))\)
for a given set of intervals.
This vector can be used as a gradient to simulate fossils under an environment-dependent model of fossil recovery using the
function <code>sim.fossils.environment</code>.
