Changes in version 1.0.0 (2016-11-16)                  

The new version 0.2.0 has C++ code integration to make the functions run
faster. It has also a higher level function to actually run the
transitions for the number of timesteps that users specify.

  - New and faster state_transition function in C++, called stRCPP.
  - stateT is the C++ specific function which is called from RCPP.
  - run_state_trans function now organizes how to run the state
    transtions in the specified number of timesteps.
  - Seperate chunks of functions to handle:
    1.  Rate to probability transformation
    2.  Calculation of cummulative probability
          - Previously, cummulative probability calculation was written
            within state_trans and stRCPP.
          - Now this is replaced with cumprob function which is written
            specifically to do that.

                 Changes in version 0.1.0 (2016-08-11)                  

This is the very first version of my package. It has 2 functionalities
for now:

  - To populate a synthetic population with states
  - To make state transitions between those states
