data.table.threads 1.0.1

New Features

• findOptimalThreadCount now has recommendedEfficiency, an argument for adjusting the slope of the recommended speedup trend/line and the recommended thread count designating point in speedup plots generated by using the plot method on an object returned by the function.
• The data used for plotting (consisting of speedup trends/lines and key points) is now accessible via attributes of the data.table returned by findOptimalThreadCount.
• Added new arguments verbose and times to runBenchmarks and findOptimalThreadCount, allowing users to enable/disable detailed message printing and specify the number of benchmark repetitions.
• S3 plot method constructs a more intuitive ggplot for data_table_threads_benchmark class objects.
• Only user-facing functions are exported.
• Examples have been updated to use namespace qualification.
• Added a function to set the thread count for data.table operations based on recommended/optimal performance (in benchmarks) of a user-specified data.table function.

Improvements

• Extensively refactored my codebase to remove redundancy.
• Made several optimizations (using data.table over data.frame, implementation of faster data aggregation operations, minimizing overhead for various function calls, etc.).
