MSTest v0.1.1

In this version I have:

• Made changes to MMC LRT related functions for obtaining null distribution of statistical test.
• Added more examples. Examples that take long to complete are commented out but serve to get familiar with usage.
• Fixed bug related to using init_theta (setting initial values of parameters) when estimating Markov models (i.e. MSARmdl(), HMmdl(), and MSVARmdl()).
• Fixed bug in MMC_bound() when k0>1
• updated DESCRIPTION file for new version.
