Reverted Ferhat's commit 23e583f95c0a5631c943c44f9116f20b91c0fb0a. The names of the dynSeries variables are stored in a column cell array.

Fixed bug in @dynSeries/align method (occuring if the second dynSeries object has more observations than the first one).

Reverted buggy commit 5366dd5cb9f546809ff21a0bd23a2ac423aac6ce by Ferhat and added call to strtrim in @dynSeries/extract method to remove leading and trailing white spaces in variable names.

Modified @dynSeries/mrdivide method so that dynSeries objects defined over different non disjoint periods can be divided.

Modified @dynSeries/mtimes method so that dynSeries objects defined over different non disjoint periods can be multiplied.

Modified @dynSeries/minus method so that dynSeries objects defined over different non disjoint periods can be substracted.

Modified @dynSeries/plus method so that dynSeries objects defined over different non disjoint periods can be added.

As in dynSeries/extract we consider a tensor product.

*Example*

Suppose that a dynSeries object contains the following set of variables

GDP_1
GDP_2
GDP_3
GDP_4
GDP_5
GDP_6
GDP_7
HICP_1
HICP_2
HICP_3
HICP_4
HICP_5
HICP_6
HICP_7
Consumption_1
Consumption_2
Consumption_3
Consumption_4
Consumption_5
Consumption_6
Consumption_7

Then the syntax:

b = a{'@GDP,HICP@_@1,2,3@'}

will instantiate a new dynSeries object containing variables:

GDP_1
GDP_2
GDP_3
HICP_1
HICP_2
HICP_3

Added the possibility to extract variables from dynSeries object using indices instead of variable names.

If ts is a dynSeries object containing variables A1, A2, A3, A4, A5, then the following syntaxes are equivalent:

ts{[1, 2, 5]}

ts{'A1','A2','A5'}

and will create a new dynSeries object made of variables A1, A2 and A5.

If called with a second input argument (dim), size returns the number of observations if dim==1 or
the number of variables if dim==2. Without this second argument, size returns the number of
observations and the number of variables.
