v1.2.1 - Filter by commits

Thanks to @JonathanGuerne for this contribution. You can now filter your results between two commits (in short SHA format) instead of a time period.

v1.1.1

This upgrade allows a command to disregard specific authors (blank attribute) and looks at all churn across the current branch for a given time period. At the end it lists all authors that committed changes during that particular timeframe.

v1.0.1

This release provides a patch to address issue #6. This issue involves the date parser of Git (https://github.com/git/git/blob/master/date.c) that provides a different result when month and day values are omitted. Appending default values for each attribute (before, after) will ensure better consistency. Providing property values such as after='2020' and before='2021' should be interpreted as after the year 2020 (so start of 2021) and before the end of 2021 (so last day of 2021).
