FlattenConditional.cpp

// Unindents the if or else statement for a conditional.
// This will apply one of the following refactorings:
//  Replace Nested Conditional with Guard Clause,
//  Remove Redundant Conditional, or
//  Reverse Conditional
// followed by
//  Remove Redundant Conditional.
// Flatten Conditional is also smart enough to recognize
// if (E) return true; else return false; and convert that to return E;.
