Solo and Mute

【Solo and Mute 】

　　Muting means a transition will be disabled. Soloed transtions are enabled and with respect to other transitions originating from the same state. You can set up mute and solo states either from the Transition Inspector, or the State Inspector (recommended), where you’ll have an overview of all the transitions from that state.

　　Muting是禁止一个转换的涵意，Soloed当自己满足转换条件时只播放自己的涵意（只和同源转换比较）。可以在Transition Inspector中设置，也可以State Inspector中设置。

　　在Animator中会有如下表现。已知的BUG是，并不是所有的solo&mute状态都会在Animator编辑器中展现。

　　如果同时勾选了mute & solo，则mute优先。
