Extended the "Rderived" library to include linpack fortran functions required to run b25.matcal-5 benchmark (enabled the benchmark in the suite).

Added linux version of the library containing fft implementation. Added b25.matfunc-1 benchmark computing fft, as well as two matcal benchmark that are currently supported,  to the benchmark suite.

create engine project (need to run mx eclipseinit); add truffle.api.ExecutionContext as RContext superclass; fix tabs
