Update of /cvsroot/rubyeclipse/org.rubypeople.rdt.core/src/org/rubypeople/rdt/internal/core/symbols
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv8784/src/org/rubypeople/rdt/internal/core/symbols

Added Files:
	Location.java SymbolIndex.java ClassSymbol.java 
Log Message:
Refactored RubyBuilder into several smaller classes. 
Wrote UTs for a few of them.
Began work on a SymbolIndex.
