flipr 0.3.3.9000

Remove any occurrence of base-R pipe operator in favor of magrittr pipe operator for now for backward compatibility with older versions of R.
Improved way of handling statistics that rely on inter-point distances.
Method $get_value() gains optional arguments keep_null_distribution and keep_permutations in case the user would like to keep track of either the permutation null distribution or the sampled permutations that have been used to produce it.
Method $get_value() now handles extra parameters to be passed to the test statistics.

The API has been changed:

An R6 class is now used to define the plausibility function, with methods that implement point estimation, confidence intervals and evaluation on grid for later plotting.
The plotting capability is still outside the class but might move into the class methods as well in the future.

Test statistics based on Inter-point distances have been added and implemented in C++ through the Rcpp package.
Test coverage is set and achieves 20% coverage for now (#3, @C-Juliette).
@C-Juliette has been added as contributor to the package.
The p-value function has been consistently renamed plausibility function to better reflects what it stands for and avoid confusion with other definitions of the p-value function in the area of functional data analysis.

Fix warning when installing the package on Oracle Solaris 10, x86, 32 bit, R-release due to pandoc version not available preventing the pvalue-function vignette from knitting properly.

Compute p-value surfaces when inferring multiple parameters at once via two_sample_pf();
Compute a point estimation for a single parameter of interest via two_sample_pe();
Compute a confidence interval for a single parameter of interest via two_sample_ci();
Automatically draw the p-value function for a single parameter of interest via two_sample_viz().

Change argument names test and combining_function to type and combine_with respectively. Add argument alternative to specify which kind of test is performed.
Add a function to compute p-value functions for sets of null hypotheses.
Draft of article illustrating the computation of p-value functions with flipr.
Add $t$, mean and Fisher test statistics.
Correct two-tail p-value computation.
Better API for pvalue function.
Added a function for two sample confidence interval for a single parameter.
Added an article about permutation inference overview.
Added dependency to the ggplot2 package for plotting features.
Added dependency to the cli package for displaying important information to the user in an elegant fashion.
Added function for point estimation of a single parameter.
Added function for confidence interval of a single parameter.
Added function for automatic plotting of the p-value function of a single parameter.
Added dependency to the withr package for properly handle local random seed generator settings.
Added dependency to the viridisLite package for using colors compatible with most common types of color blindness.

Fix warning when installing the package on Oracle Solaris 10, x86, 32 bit, R-release due to pandoc version not available.
Switch to GPL-3 license because purrr dependency is GPL-3 licensed.
