Version 1.7.0

Highlight: New UICircularProgressRingView.minValue property.

• Add ability to set a range of values for the ring, unlike before where only maxValue could be set. You can now use the new minValue to specify a range that the value can fall between. Read the docs to learn about any issues that may arise with setting a value less than minValue.
• Fixed bugs related to how many degrees the inner ring for the progress ring draws. Everything should exact now even if not using the fullCircle property.
• Fixed a bug which allowed setting a value less than zero. Read the docs to learn why this was an issue.
• Refactored some unused code and tidied things up a bit
• Regenerated documentation using Jazzy
