check if quickview's immediate parent is unary for items/rows navigation

[vineetsemwal]

there should be a check to see if quickview's immediate parent is unary for items navigation ie. in the case where reuse constant provided is Reuse.ALL or Reuse.ITEMSNAVIGATION
the check should see if parent has only one child and of course that child is quickview,this would help user from getting unexpected result later else user can have children/rows created after immediate parent's other children.

fixed ,from now on if immediate parent of quickview has any other child then in case of items/rows navigation, exception will be thrown with message "the markupcontainer to which quickview is attached should have quickview as its only child"

[vineetsemwal]

this restriction is removed in master now , quickview can now be added boundaries
ie. one component can be added to represent start of quickview and one component can be added to represent end of quickview ,demonstrated in examples

this is fixed and available in 6.14.0
