TernaryPatcher (fb-contrib api)

```
public final class TernaryPatcher
extends java.lang.Object
```
restores OpcodeStack Item's userValues when a ternary is processed. This class is required because Findbugs has a bug whereby it strips the user value field from all OpcodeStack items when a GOTO is processed when items are on the stack. Normally this is not the case, but in the case of ternary handling there may be N items on the stack before what the ternary pushes. Now clearly the uservalue should be stripped for items pushed on by both branches of the ternary, but items that were on the stack before the ternary was executed should be left alone. This is currently not happening in findbugs. So this class saves off user values across a GOTO involved with a ternary and restores them appropriately.

Modifier and Type	Method and Description
`static void`	`post(edu.umd.cs.findbugs.OpcodeStack stack, int opcode)` called after the execution of the parent OpcodeStack.sawOpcode, to restore the user values after the GOTO or GOTO_W's mergeJumps were processed
`static void`	`pre(edu.umd.cs.findbugs.OpcodeStack stack, int opcode)` called before the execution of the parent OpcodeStack.sawOpcode() to save user values if the opcode is a GOTO or GOTO_W.
