/**
* GridView columns or rows can accept comma separated strings with
* absolute pixel value, percent value and star (*).
*
* For example, 20% of total width for first column, 200 pixel for last column
* and rest of the space is for middle = "20%, *, 200"
*
* You can have only one star specification.
* @example
* <AtomGridView
* rows="50,*"
* columns="20%, 5, *, 200">
*
* <!-- Header spans for three columns in first row -->
* <header row="0" column="0:3"></header>
*
* <!-- menu is on first column -->
* <menu row="1" column="0"></menu>
*
* <!-- Grid splitter splits 1st and 3rd column and itself lies in 2nd column -->
* <AtomGridSplitter row="1" column="1" direction="vertical" />
*
* <!-- Section fills remaining area -->
* <section row="1" column="2"></section>
*
* <!-- Help sits on last column -->
* <Help row="1" column="3"></Help>
