There are datastructures and functions that are

shared between interfaces (PGIP and GUI). For example

history should be stored in the same way by both , so

that one could in principle switch from one to the other.

Also there is code that gets duplicated just because

both PGIP and GUI need it and the interfaces should be

independent one from the other. This folder will contain

all common functions / datastructures.

Initially I wanted to make a new interface (abstract interface)

that would do history management and report all results through

strings. The above interfaces would just use this interface

to transform the development graph, and use the string to

find out results about the commands. But I noticed that

GUI and PGIP are so different in how they function this

would imply altering to much both interfaces, and decided

just to have common datastructures and functions that could

be shared.

Note that PGIP interface is done so that it can support any

other type of interface that comunicates through text ( for

example remotely through xml blocks send between user/hets,

through files that contains commands .. etc.)
