bug in @dynSeries/subsasgn.m
Updating a subsample of a time series results in duplication of the variables:
Example: z = dynSeries((1:5)',dynDate('1990Q1'),'Z'); d = dynDate('1990Q2'):dynDate('1990Q4'); z(d) = z(d) + 10
This is obviously related to merge_dynSeries_objects = 1; at the beginning of subsasgn.m that triggers merge() at the end of the function and which shouldn't happen in this case. I'm not sure how to fix it without breaking something else.
