Subprograms used in the main program
- rules_functions: Functions related to the rules of thumb, e.g. applying them to a vector of intensities
- finding_nash_equil_normalformgame_cluster: Functions to compute the nash equil of a normal form game
- correlation_functions:  Functions to transform uniform correlations in to normal correlations, and create
the normal correlation matrix
- correlation_agend: Extra function to generate the  normal correlations for the 
nomination types we care about as a function of the uniform correlations
- intensities_generation: Functions to generate intensities with given properties,
for instance the correlations desired
- welfare_calc: Functions to do operations on  the final matrix of intensities
and compute the welfare measures
