CFunc

This class represents context variable and register value of a functional type A => B. When variable or register is accessed using getVar[A => B](id).get or box.getReg[A => B].get an instance of this class is returned.

It internally transforms a given tree into executable function. This it similar to what happens during validation of propositions in the input boxes: - size check of underlying ErgoTree against limits - construction of calcF and costF graphs, both are stored together with resulting function. - check the types of calcF graph to be compatible with expected types A and B If anything goes wrong, this operation fails and if it is used in the script, the script also fails.

When f is obtained as val f = getVar[Int => Int](id).get then any application f(x) involves size estimation using underlying costF(x).

The cost of creating resulting function but not its execution.
The cost of creating resulting function but not its execution. Thus it is expected to be small. It can be increased if useful cases are found such that tree should contains heavy operations.
