Utility to replace whitespaces with special characters.
The main purpose is to enable properly displaying of whitespaces in HTML.

This utility takes as an input a whitespace character, like " ", "\t" and replaces it with
a unicode character, like "\u00A0" (Non-breaking whitespace). The replacement is handled
in the following manner:
<ul>
		<li> If there's a single space (" ") it leaves it as it is. HTML handles properly single whitespaces. </li>
		<li> If there are multiple, consecutive whitespaces "     " or "\t"), it starts to alternate a space with
	\u00A0 (Non-breaking whitespace) character. </li>
		<li> If there is a tab character, it's first converted to 2 spaces and then processed by the steps above. </li>
</ul>

<b> Note: </b> This utility handles " " (consecutive spaces) and "\t" (tabs). New lines ("\n") would not be handled.

@example
sap.ui.require(["sap/base/strings/whitespaceReplacer"], function(whitespaceReplacer){
     whitespaceReplacer("Foo    bar"); // "Foo \u00A0 \u00A0bar"
});
