+Remark: 
+ The following common procedures from NR are used here, that can probably
+ easily replaced from other sources:
+ .
+  * gammln(xx): natural log of gamma function.
+  * gasdev(seed): normally distributed deviate of zero mean and unit var
+  * poidev(xm, seed): Poisson deviates for a given mean.
+ .
+ Also, the following routines are used only in the noao/rv package.
+ We could just remove that package from the distribution, or we find a
+ replacement for four1 (the two other just call this).
+ .
+  * four1(data, nn, isign): Replaces DATA by it's discrete transform
+  * realft(data, N, isign): Fourier Transform of a set of 2N data points.
+  * twofft(data1, data2, fft1, fft2, N): calls four1()
+ .
+ Then we have LU decomposition functions, used in pkg/utilities/stxtools/xtwcs.x:
+ .
+  * ludcmp(a, n, np, indx, d)
+  * lubksb(a, n, np, indx, b)
+  * luminv(a, n, np)
+ .
+ and Levenberg-Marquardt nonlinear chi square minimization:
+ .
+  * mr_eval(x, y, npts, params, flags, np, a, delta, nfit, chisq)
+  * mr_invert(a, b, n)
+  * mr_solve(x, y, npts, params, flags, np, nfit, mr, chisq)
+ .
+ Maybe this could be replaced by cminpack?
