CHANGES IN VERSION 1.17.1
------------------------
 o update IC data for next release <2013-03-08, Fri>
 o after removing NA row/col of similarity matrix, if only one row/col remains, R will turn it to be a vector, and combineScore function will not work properly. This bug was fixed <2013-01-11, Fri>
 o bug fixed of infoContentMethod, now return NA when ID is not belong to the ontology <2012-10-11, Thu>

CHANGES IN VERSION 1.15.3
------------------------
 o remove all the S4 classes and methods <2012-09-12, Wed>
 o add progress bar for mgeneSim <2012-09-12, Wed> 
 o re-implement calculating semantic values in Wang's method <2012-09-12, Wed>
 o update IC data for next release <2012-09-12, Wed>

   other ontological semantic similarity measurement <2012-06-14, Thu>
 o update vignette. <2012-06-14, Thu>

CHANGES IN VERSION 1.13.6
------------------------
 o remove dependency of organism annotation packages. <2012-03-09, Fri>
   User not need to install all these annotation packages for using GOSemSim.
