Functions.EnableArrayIndexCheck Method

Suppress Array Index check to be compatible with Visual Objects
In some situations Visual Objects did not throw a runtime error when you were accessing a non existing array element.
You can enable this (mis)behaviour in X# by disabling the array index checks.
The default behavior is to generate an error when you access array indices out of the existing range.
