#17 Refactoring functionality

[Pasha Abolmasov]

The most important operations are:
Intoduce graph. Means select some tops and agregate them into new graph. Need to check data dependencies, flowchart dependencies, find the same graph stucture in related graphs.
Inline graph. Means replase one top with actual graph plased in it. Inline may be local and global. Local inline replases only one top. Global replases averywhere.
Easy modification of basemodules (easy modification of signature, re-registration)
