Proposed name for the geometry file: pams/geometry/ecalgeo/**ecalgeo1.g**

List of changes

- CAir bug fixed
- Increased size of mother volume containing SMD strips
- Added material to front and back of SMD planes (material wrapping SMD planes)
- Added SMD spacer layers
- Introduced sector overlaps closer to the "as build" geometry
- Birk's law constants for SMD strips corrected
- Some dimention paramaters tuned to that in real geometry
- Code reorganized and commented

Note:

Lead alloy mixtures are not implemented

due to the problem with mixture in GSTAR/Geant (see below)

Resulting improvements in the simulated EEMC response

- Geometry configuration is closer to the "as build" geometry
- Correct simulation of the transverse shower shape profile
- Realistic (close to 5%) sampling fraction
- More realistic simulation of the tower energy profile (with LOW_EM option)

EEMC sampling fraction nonlinearities and CAir bug

EEMC geometry reshape
