Add ability to "filter out" buried net in TabEquipotentials. Definition: A buried net is a net that has no components at the top Cell level. Typically example is a wire internal to a standard cell. Those nets, while part of the complete design (flat) are not part of the top netlist, and we may want not to see it. A buried net is slighly different from a deep net. While a deepnet is also not reaching the top level cell, we created it at top level to be processed by the router (virtual flatten).

Full transhierarchical implementation done. * New: Equipotential elements includes now: 1. Components at the top level (the cell owning the Equi). 2. Nets at the top level. If an equi include all the components of a Net, own the Net, not all it's individual components. 3. Other equipotentials from the Instances immediatey below. Thoses equis should be equivalents to the Plug of the Net. They are stored in the form of Occurrences <Instance,Equi>, the relation is stored on that Occurrence. * New: Equipotential::getFlatComponents(), a collection to recursively get all the *component* occurrences of the equi. Transhierarchically. Go through components, nets components, and recursively through the child equis. * New: EquipotentialRelation, the master of this relation is the Equipotential and the slaves, all its elements. * Change: In Tile, in case the tile is build on a deep component, we trace up the Equipotential it belongs to in the Instance level immediately belonging to the Cell under extraction. They must exists as we extract from bottom to top all the master cells. So we have, for that tile an Occurrence <Instance,Equi> that we can store in the current Equi level. * Change/Bug: In Tile, add an Id to be reliably sort the tiles in the IntervalTree. As we replaced the tile component occurrence by a <Instance,Equi> we were having multiple tiles with the same equi. This was causing havoc again in the IntervalTree. Should add a check in the RbTree for elements with the exact same key, but that would imply passing a new template parameter for the "equal" function.
