[OmniFaces utilities 2.0] Create an integer array which starts/ends at the given integers, inclusive

---

[OmniFaces utilities] The createIntegerArray() function creates and return an integer array which starts at the given integer and ends at the given integer, inclusive. This is useful if you want to for example populate a <f:selectItems> which shows an integer range to represent days and years. If the begin is greater than end, then the array will be decremental. If the begin equals end, then the array will contain only one item.

// create an integer array from 10 to 20

<ui:repeat value="#{of:createIntegerArray(10, 20)}" var="i" varStatus="loop">

 #{i}#{!loop.last ? ', ' : ''}

</ui:repeat>

Output: 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20

// create another dummy array of size 5

<table border="1">

 <tr>

  <td>Value</td>

  <td>Index</td>

  <td>First</td>

  <td>Last</td>

  <td>Begin</td>

  <td>End</td>

  <td>Step</td>

  <td>Current</td>

  <td>Even</td>

  <td>Odd</td>

 </tr>          

 <ui:repeat value="#{of:createIntegerArray(10, 20)}" var="i" varStatus="vs">         

  <tr>

   <td>#{i}</td>

   <td> #{vs.index}</td>

   <td>#{vs.first}</td>

   <td>#{vs.last}</td>

   <td>#{vs.begin}</td>

   <td>#{vs.end}</td>

   <td>#{vs.step}</td>

   <td>#{vs.current}</td>

   <td>#{vs.even}</td>

   <td>#{vs.odd}</td>
