This non-framework package simulates the RunIIb level 1 calorimeter trigger
sliding windows algorithm.  Compiling the package will create a library that
is needed by trigger_rate_tool for RunIIb AndOr terms and rates.  
In the version v00-00-01, it is designed to run in p17.02.00
To turn on L1Cal Run2b trigger emulation, turn on the Emulate_Run2BL1Cal 
rcp flag in trigger_rate_tool/rcp/GenerateTriggerTable.rcp 

There are 3 EM algorithms and 2 jet algorithms implemented.  
EM 1,0,1 -  1x1 ROI, 0 LM separation, 1 TT isolation ring
EM 2,0,1 -  2x2 ROI, 0 LM separation, 1 TT isolation ring
EM A,0,s - Atlas 2x1 ROI, 0 LM separation, sandwich TT isolation region

Jet 1,0,0 - 1x1 ROI, 0 LM separation, 0 TT isolation ring
Jet 2,1,1 - 2x2 ROI, 1 LM separation, 1 TT isolation ring

The isolation region is defined as a ring (or disconnected sandwich for Atlas) in EM section only.
The EM-fraction is defined as a ratio of the EM and HAD energies in the ROI only.

Examples:
You can access the trigger term for an 11 GeV electron found using EM A,0,s algorithm
with EM fraction > 8 and  isolation < 0.2 with the term CEMxEMfracAtlas(1,11,8,0.2)

You can access the trigger term for a diem event with each electron having Et>6,
no isolation or EM fraction cuts, and with the sum Et of the two electrons Et_sum > 18 GeV
with the term DIEM_SW(6,0,100,18).  
                        |  |--> EM fraction
                        ------> isolation

You can access the trigger term for a 20 GeV jet found using the Jet 2,1,1 algorithm
with fabs(eta) < 3.2 with the term CJT_SW2x2(1,20.0,3.2)

You can access a 3-jet trigger term with each jet having Et>4, fabs(eta)<2.4 with
the term CJT_SW2x2(3,4.0,2.4)
