Added overload subsasgn method in dynSeries class. 

Following syntax:

ts{'GDP_US'} = ts.{'GDP_US'}.log

applies the log function to the variable GDP_US in the dynSeries object ts. Note that this works on an arbitrary number of variables and that regular expressions can be used (see previous commits).
