Dot Color Behavior Update

As suggested in PR #121, because graph dot alpha is not an editable
property, the default internal value is now 1.0 (100%). You may change
the alpha of dots by specifying a UIColor for the `colorPoint` property
with an alpha value. The new default value of `colorPoint` is white at
0.7 (70%) alpha.
