rcpptimer 1.1.0

Improvements

Add new Rcpp::CppTimer::ScopedTimer class. This can be used to time the lifespan of an object until it goes out of scope. This is useful for timing the duration of a function or a loop. The fibonacci example was updated to use this new class.
Warn about timers that are not stopped when aggregate is called (no matching toc() statement).
Warn about timers for which no matching tic() statement was found.
Add verbose parameter to the Timer class to control whether above warnings should be printed or not (defaults to true).
Add introductory vignette to the package.

Fixed cases where only toc() was called without matching tic().
- This led to a segfault in the previous version.
Fix reset() method which was not working properly in some cases where timers spread out over multiple methods.
Fix non-default constructors of the Timer class. They were not working properly in the previous version.

This is the initial release of rcpptimer. It is based on RcppClock but contains a number of improvements:

OpenMP support
Auomatically returns results to R as soon as the C++ Object goes out of scope
Fast computation of Mean and Standard Deviation of the results in C++
Uses tic and toc instead of tick and tock to be consistent with R's tictoc package
Allways reports microseconds resolution
Many more performance improvements
