Added new routine that converts a string of Key-Value pairs in a cell.

matlab/read_key_value_string.m

+function c = read_key_value_string(s)
+
+% Transforms a string of Key-Value options as returned by the preprocessor (for optim option in the
+% estimation command) into a cell (first column for the option name ans second column for the
+% option value).
