standardize function

Standardizes a Numeric Matrix by Columns.

Sometimes it is desirable to have all variables to have mean 0 and standard deviation 1. This function rescales the values in such a way.

If the argument is not a matrix, the function tries to convert the object into a matrix. For example, it works smoothly for xts objects.
