Computes the y values describing a Gaussian distribution given a range of x values and parameters for mu, sigma, and area. A tail may be introduced into the curve to simulate the behavior of some chromatography peaks.

1	gaussCurve(x, area, mu, sigma, tail)

`x`	A vector of x values which will be used to compute the corresponding y values. Use enough to give good resolution.
`area`	The area of the peak, in arbitrary units.
`mu`	The position of the peak. Must fall in the range of x, of course.
`sigma`	The standard deviation of the peak.
`tail`	A value describing any tailing desired. If NA, no tailing is applied.

A vector of y values corresponding to the x values supplied.

### A pure Gaussian curve

myx <- seq(0, 100, length.out = 1000) # use lots of point for resolution
myy <- gaussCurve(x = myx, area = 1, mu = 40, sigma = 1.5, tail = NA)
plot(myx, myy, type = "l", main = "Pure Gaussian Curve")

### Now with tailing

myy2 <- gaussCurve(x = myx, area = 1, mu = 40, sigma = 1.5, tail = 0.1)
plot(myx, myy2, type = "l", main = "Gaussian Curve with Tailing")
