// Class description:
//
// Base class for `touchable' objects capable of maintaining an
// association between parts of the geometrical hierarchy (volumes
// &/or solids) and their resultant transformation.
//
// Utilisation:
// -----------
// A touchable is a geometrical volume (solid) which has a unique
// placement in a detector description. It is an abstract base class which
// can be implemented in a variety of ways. Each way must provide the
// capabilities of obtaining the transformation and solid that is described
// by the touchable.
//
// All G4VTouchable implementations must respond to the two following
// "requests":
//
// 1) GetTranslation and GetRotation that return the components of the
// volume's transformation.
//
// 2) GetSolid that gives the solid of this touchable.
//
//
// Additional capabilities are available from implementations with more
// information. These have a default implementation that causes an exception.
//
// Several capabilities are available from touchables with physical volumes:
//
// 3) GetVolume gives the physical volume.
//
// 4) GetReplicaNumber or GetCopyNumber gives the copy number of the
// physical volume, either if it is replicated or not.
//
// Touchables that store volume hierarchy (history) have the whole stack of
// parent volumes available. Thus it is possible to add a little more state
// in order to extend its functionality. We add a "pointer" to a level and a
// member function to move the level in this stack. Then calling the above
// member functions for another level, the information for that level can be
// retrieved.
//
// The top of the history tree is, by convention, the world volume.
//
// 5) GetHistoryDepth gives the depth of the history tree.
//
// 6) GetReplicaNumber/GetCopyNumber, GetVolume, GetTranslation and
// GetRotation each can be called with a depth argument.
// They return the value of the respective level of the touchable.
//
// 7) MoveUpHistory(num) moves the current pointer inside the touchable
// to point "num" levels up the history tree. Thus, eg, calling
// it with num=1 will cause the internal pointer to move to the mother
// of the current volume.
// NOTE: this method MODIFIES the touchable.
//
// An update method, with different arguments is available, so that the
// information in a touchable can be updated:
//
// 8) UpdateYourself takes a physical volume pointer and can additionally
// take a NavigationHistory.
// A G4TouchableHistory object.
