ThreeColumnTextBar class
A ThreeColumnTextBar is typically used to display a textual summary bar along the top of the device screen. It has 3 columns marked as c1, c2, and c3. Each column in turn has two fixed rows, wherein, the first row is used to display a label which defines the data that is contained within the second row. The labelText size is smaller than the dataTextSize. Examples where it can be used includes, to display income / expense summary in a Personal Finance Management app, whether forecast for 3 days in a weather app, etc. Keep in mind that it only displays the information using 'text', hence, graphics and other widgets are not supported, as of yet.

- It allows you to create the most configurable ThreeColumnTextBar with customizable default grey background. The labelText and dataText are set to blue and black colors, respectively. Also borderRadius is set to 0 and hangingDivider is visible. The prefix of c1, c2, and c3 represent Column #1, Column #2, and Column #3, respectively. Note: The minimum holder hieght is 60px on any device.
