Giving users control over min/maxIncluded for axis titles by including them into SideTitles (addresses #906)

[sczesla]

Including titles (labels) for the minimum and maximum data value is sometimes not desirable (see #906). The iterateThroughAxis routine (in axis_chart_helpers.dart) provides the logic for optional inclusion of the minimum and maximum already. This PR gives users control over these flags by incorporating them into SideTitles.

You haven't used the properties that you defined. I think you need to add them here. Also, please read the contribution guideline carefully, you need to write unit-tests

Thanks for the feedback!

I don't think so. Your link points to the defaults. The values are being used, possibly overwriting those defaults , when iterateThroughAxis is called here

Also, please read the contribution guideline carefully, you need to write unit-tests

Right. I added a test of the effect of setting the parameters when plotting, fixed formatting issues, edited the CHANGELOG, and rebased.

Cheers
