/**
* Indicates the rotation of the Button in degrees, from its original orientation. Values from 0 to 180 represent clockwise rotation; values from 0 to -180 represent counterclockwise rotation.
* Values outside this range are added to or subtracted from 360 to obtain a value within the range. For example, the statement player.angle = 450 is the same as player.angle = 90.
* If you wish to work in radians instead of degrees use the rotation property instead. Working in radians is also a little faster as it doesn't have to convert the angle.
* 
* @name Phaser.Button#angle
