[kepler-dev] [Bug 3173] - Improve data frame handling between RExpression actors

[Dan Higgins]

Ben (and others)

    I deliberately avoided the R serialization approach when I 
originally implemented the RExpression actor because the serialized 
dataframe cannot be accessed by non-R actors, while the text file table 
that was previously written could be read by other Kepler actors. I fear 
making Kepler too R-centric will lessen its general usefulness.
