Compile server for GNU R bytecode

This is implementation of compile server of GNU R bytecode done as a proof of concept. To run the server itself there should not be any additional dependencies other then those handled by Cargo. To run the test and benchmark you have to have GNU R interpreter installed and be able to run the Rscipt command. To be sure that the test can be run all the R scripts in root folder should be executable.

Running

To run tests

mkdir temp # not necessary if it already exists
cargo test

To run benchmark

cargo run -r -- -b

To run server

cargo run -r -- -s

Compile closure from RDS file

cargo run -r -- [file] -c

Output the representation of SEXP serialized in RDS file

cargo run -r -- [file] -d
