First version of generator.

Contains 2 types of generators:

1. Matrix generator: generates net using adjacency matrix. Takes as parameters:
   1. Inner cells number;
   2. Primary inputs number;
   3. Primary outputs number;
   4. Net base (possible operations)
   5. Seed
2. Layers generator: generates net layer by layer. Takes as parameters:
   1. Number of gates on each layer;
   2. Primary inputs number;
   3. Primary outputs number;
   4. Net base (possible operations)
   5. Seed

It is possible to set fanin limits for both generators (allowed number of input cells for each cell of the resulting net).
