/**
* Variable assigning ViewHelper
*
* Assigns one template variable which will exist also
* after the ViewHelper is done rendering, i.e. adds
* template variables.
*
* If you require a variable assignment which does not
* exist in the template after a piece of Fluid code
* is rendered, consider using ``f:alias`` ViewHelper instead.
*
* Usages:
*
* ::
*
* {f:variable(name: 'myvariable', value: 'some value')}
* <f:variable name="myvariable">some value</f:variable>
* {oldvariable -> f:format.htmlspecialchars() -> f:variable(name: 'newvariable')}
* <f:variable name="myvariable"><f:format.htmlspecialchars>{oldvariable}</f:format.htmlspecialchars></f:variable>
