Chiasm-Charts v0.1.2

This release of chiasm-charts adds dynamic scale types chat change based on the input data. This allows, for example, ordinal scales on a scatter plot.

Also, the axis labels are now relative to the outer box, rather than relative to the margin. This allows the user to interactively adjust the margin such that axis tick labels do not overlap with the axis labels.

Color options have also been included in the bar chart, and a new "backgroundColor" mixin has been introduced.
