operator <= method
Creates a Constraint by using this member as the left hand side expression and the argument as the right hand side Expression of a Constraint with a Relation.lessThanOrEqualTo relationship between the two.
For example: rightEdgeOfA <= leftEdgeOfB
would read, "the entities A and
B are stacked left to right."
Implementation
Constraint operator <=(EquationMember m) => asExpression() <= m;
