Summary: Minor tick marks on DateAxis

Initial Comment:
I needed minor tick marks on my horizontal DateAxis, illustrated at http://picasaweb.google.com/amickish/JFreeChart/photo#5153499160795464114
Specifically, I wanted major tick marks every year, and minor tick marks every month.

So I overrode refreshTicks() in my DateAxis to add minor a minor DateTick for every month.

To support minor tick marks, I changed these 3 files in package org.jfree.chart.axis:

  DateTick.java: a constructor that takes a TickType

  ValueAxis.java: enhanced drawTickMarksAndLabels()
  to draw minor tick marks

  Axis.java: public methods and private members that
  activate minor tick marks

These changes should have no effect on pre-existing user code.  The old methods like isTickMarksVisible() still control major tick marks.

The new minor tick mark methods have names like isTickMarksMinorVisible() corresponding to the old (major) names.
