- Added new experiments (step function for fundamental; agents with
different latency). 
- Added Main function to ConstantFundamentalSameLatency. The experiment
can be run from command line by exporting a jar file. However, this does
not support the execution of the R script within java, as the library is
not included in the jar for some reason (or maybe RHOME is not set
properly).
