If the names of the variables are not provided when instantiating a dynSeries object
then the default name is of the form Variable_i (i=1,...,N, where N is the number of
variables in the dataset).

+ Prefix variable names with QGROWTH_
+ Prefix tex variable names with \delta_i with i=nothing or 3 depending on the frequency.

 + Prefix variable names with YGROWTH_
 + Prefix tex variable names with \delta_i with i=nothing, 4, 12  or 52 depending on the frequency.

+ Prefix variable names with QDIFF_
+ Prefix tex variable names with \Delta_i with i=nothing or 3 depending on the frequency.

 + Prefix variable names with YDIFF_
 + Prefix tex variable names with \Delta_i with i=nothing, 4, 12 or 52 depending on the frequency.

 + Prefix variable names with the minus symbol.
 + Set tex member.

If ts is a dynSeries object, then the following syntax is valid:

t0 = dynDate('1950Q1') ;
t1 = dynDate('2000Q3') ;

range = t0:t1 ;
ds = ts(range);

Note that the dates in range do not need to be contiguous or sorted in increasing order.

  dynDates; dynDate can be initialized with a single dynDate

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).

The following syntax

A.name{i}

where A is a dynSeries object, returns the name of the i-th variable in A.
