Implement a challenge system, MLB

[BigGref]

I think the challenge system is the likely next step.

2 challenges per coach, in those situations outlined before in this thread, if those two are successful they may get a third. 90 seconds or whatever, indisputable evidence, blah, blah...

I think this may actually help with some manager confrontations, if they come out on a judgement call the conversation is simple:
"what did you see?"
"he beat the tag, anything else sir?"
Anything else by coach besides "no thank you" and "I want to challenge" is end of discussion, then ejection
