Added more boolean expressions.

#3, #26

Changes

• ^^
• <
• >
• <=
• >=

Usage

Adds ^^, <, >, <=, and >= operators

// Declare boolean refrences
const a = new cgl.Reference(
  new cgl.InterfaceVariable(cgl.Qualifier.In, new cgl.Variable(cgl.Type.Bool, 'a'))
);
const b = new cgl.Reference(
  new cgl.InterfaceVariable(cgl.Qualifier.In, new cgl.Variable(cgl.Type.Bool, 'b'))
);

// XOR expression
// (a ^^ b)
new cgl.XorExpression(a, b);

// Less than expression
// (a < b)
new cgl.LessThanExpression(a, b);

// Less than equal expression
// (a <= b)
new cgl.LessThanEqualExpression(a, b);

// Greater than expression
// (a > b)
new cgl.GreaterThanExpression(a, b);

// Greater than equal expression
// (a >= b)
new cgl.GreaterThanEqualExpression(a, b);

TIL ^^ is logical XOR and that there's more than just ^ for bitwise XOR
