Add testing for Python 2.6, 2.7, 3.3.

By docstring instructions, add an example of the code being used. More detail can be added to the shapes/types of the individual inputs and outputs. Each can get a one line description.

| y_array1_rand = y_array1 + (np.random.randn(len(y_array1)) * unc1) |

Line by line comments would be helpful, describing what the individual line achieves. For example, this line 'wiggles' within the uncertainty.
| unc = np.asarray(unc_array) | ||
| avg_unc = np.sum(unc) / len(unc) | ||
| if avg_unc > 4.0: | ||
| unc = 1.0 / unc |

the relationship of SNR to uncertainty is unc=1/SNR? Add comment next to if statement making this clear - that an average above 4 indicates the array is SNR data

Comment w is wavelength, f is frequency, etc.

| shifted_wavelength = wavelength * (1. - (rv / 2.99792458e5)) |

What is that number? Comment - also if it is a known constant try using astropy.constants, if the attached units give trouble, at end of variable put variable.value()

Does it matter which argument spectrum is being normalized to the other?

update this function to docstring convention

good description of variables - add to above functions

Well commented, but no docstrings.
