Feature 404 v3.0.0 beta6 (#406)

* Per #404, modifying version and dates

* Per #404, updating release notes

* Adding self as an argument to calculate_statistic to attempt to resolve error with METplotpy run

* Removing self as an argument to calculate_statistic to attempt to resolve error with METplotpy run because this would need to be done in the develop branch

* calculate_statistic() is not a SumStat class method.  Remove the logging, which requires the logger that is created in the constructor of the SumStat class.  Instead, raise an exception with a detailed message.
