The pointer Type

	For developer use only
	The pointer type is for use by breve and plugin developers only.

pointer variables store C-style pointers to internal data. They are not used for writing simulations in steve and are only used by breve developers and plugin authors.

pointer variables are only useful in the context of interacting with internal C-style function calls: they do not contain methods, variables or any other meaning in the context of most steve code. Like objects, however, pointers can be tested to see if they are NULL (0), but cannot be used in mathematical expressions. That is to say that pointers have a meaning in a boolean context of control structures such as if and while (as well as the logical operators && and ||).

As in C, copying a pointer (assigning it to another variable) will not copy the data it points to.
