Is the action allowed by the game of no-limit Texas Hold'em?
It is not allowed if:
-you need to move more chips to the table than you have in your stack to perform this action (unless you go all-in)
-it's a raise action but the amount of chips raised is smaller than the highest raise so far this deal (unless you go all-in)
-it's a check action while the call amount is higher than 0

action: the action to test
stack: stack the player currently has (excludes his wager)
wager: chips the player has contributed to the pot this deal so far
highestWager: the amount of wager of the player with highest wager (needed to know amount required to call)
highestRaise: the highest raise amount so far during this deal (the amount raised above the call amount) (needed to exclude small raises)

/*
Is this an all-in action, and, is it valid?
It is not consudered valid if it's a raise action and the amount of chips is larger than your stack. It
must be exactly equal to be an all-in action.
