new stp_logger macro
failing if a dataset already existed called 'append' also adding output and stop to prevent infinite loop.
Occasionally an SCD2 type load will show that two seemingly identical
records are in fact different. This macro will compare two records
and convert each field to a binary value for exact comparison.

Analysts may inadvertelntly include collinear variables in a regression. (Collinearity means that one variable is a constant plus a weighted sum of other variables.) To help users figure out which variables are collinear, the %collinear macro reports how much of the variance in each variable can be explained by the others (R2). If R2=1, then the variable in question is collinear with other variables. The macro is invoked as follows: %collinear (dataset=mydataset, vars=x1 x2 etc); where mydataset is the dataset you are working with and x1 x2 etc is a list of variables including some that may be collinear.
