Detailed Description

                                                                         <br>

Phys_Geom_Database class make connection between detector geometry and
Particle-Flow reconstruction package.

It might be forms as geometry driver in Mokka.
Even more - maybe better create it at the simulation
step and put it onto LCIO simulation output file.

*************************************************************
It strongly depends on the PARTICULAR detector geometry.
GEAR is used to get that particular detector geometry
"The Latest" and unique link to geometry before
the PFA reconstruction procedure
****************************************************************

It also may consist of all reconstruction tuning parameters.
Some of them depends on zone number, some does not.

Usage:

PGdb::ZONE PGdb::get_zone(Point3D &p);
Function return zone "number" (enum type)
for any arbitrary 3-d point

if Hit h is a hit than h.cp is Caretsian coordinates of hit;

ZONE i=PGDB.get_zone(h.cp);
...
int iel = pgdb[i].det_mat;
BooElemens[pgdb[i].det_mat];
double ecal_inn_rad;
pgdb[PGDB::ECAL1_BAR].r_inner;
