Using RCallServicesREngineWrapper to eval each expression in the environment gMCP:::gMCPenv instead of the global environment.
Added JGR.jar as build dependency.
Updated TODO regarding JHLIR.
New method evalInGlobalEnv for evaluations in the global environment (only used if requested by user).
Added "silent=TRUE" to 'try' call in graph2latex.
Wrapper for 'evalVoid'.
Changed rcs to wrapper subclass to call '*InGlobalEnv' methods.
Changed appropriate calls to 'evalVoidInGlobalEnv' - still open are: i) use specified environment instead of global env. ii) Don't save temporary graphs there.
Merge branch 'gMCPenv'
