Additions to PHPExcel_Chart_Layout to allow manual 3D rotations

[jocull]

Today I made additions that allow manual rotations of a 3D chart, such as a pie chart. These may not be included in exactly the correct places, but they are useful for me as-is.

Using a layout sample like this...

$layoutPlotArea = new PHPExcel_Chart_Layout();
$layoutPlotArea->setManual3dAlign(true);
$layoutPlotArea->setXRotation(50);
$layoutPlotArea->setYRotation(0);
$layoutPlotArea->setPerspective(15);
$plotArea = new PHPExcel_Chart_PlotArea($layoutPlotArea, array($series1));

Results in XML additions of,,,

<c:view3D>
    <c:rotX val="50"/>
    <c:rotY val="0"/>
    <c:rAngAx val="0"/>
    <c:perspective val="15"/>
</c:view3D>

Thanks, will take a look at this - since I introduced charts as an experimental feature I've been getting more and more demands to expand charting features, so this will be a nice first step
