Search control functions

The FlexiLayout language provides the following functions for controlling element searches and hypothesis generation.

Definition	Description
`Void Optional( Real q1, Real q2 )`	Makes an element optional. The `q1` parameter sets the quality of the null hypothesis. The `q2` parameter sets the criterion for formulating the null hypothesis: the null hypothesis is formulated if no other hypotheses are created whose qualities exceed a certain threshold.
`Void StopIfFound( Logic Value = true )`	Stops generating hypotheses in the branch if it contains a non-null hypothesis for the given element. For more information, see Required, optional, and prohibited elements.
`Void DontFind()`	Tells FlexiLayout Studio not to look for an element. If the element is optional, only the null hypothesis is formulated.
`Void MaxHypothesesCount( Int )`	Sets the maximum number of hypotheses for an element.
