EEMC Tower Swaps

During the EEMC MIP calibration, we find that some of the EEMC cables are swaped.

Swaps in database:(This has been implemented during the production, you do not need to worried about these.)
1. mapping=S1 rot, P1 as in sect=5, swap TA4-5, QA11-B2, JB;
2. mapping=swap V209:216, V216-280, V265:272, Bob
3. mapping=swap 10TD04 with 10TD06, Ting and Mike(Not valid before 2015-08-13)

Swap towers found From MIP calibration: 
 2009 pp200: 
 10TD06 <=> 10TD04 
 11TE10 <=> 11TE12

 2012 & 2013:
 10TD04  <=> 10TD06  
 11TC05  <=> 11TC07
 11TB04  <=> 11TB06
 04TB01  <=> 04TB12
 04TB02  <=> 04TB11
 04TB03  <=> 04TB10
 04TB04  <=> 04TB09
 04TB05  <=> 04TB08
 04TB06  <=> 04TB07

Suggestion:
You can remap the towers in your own analysis.
For example, in Jet analysis, add a small piece of code before you record the tower Id in StRoot/StJetMaker/mudst/StjEEMCMuDst.cxx at line 84.
