var arg1 = "x"
var arg2 = "z"
arg1 == arg2

_.includes(): takes two arguments and determines whether the first contains the second

var arg2 = "Greg"
_.includes(arg1,arg2) 

categorical: takes either a single options argument with values specified for ps (i.e., a list of probabilities) and vs (i.e., a list of variables), or two lists (the first a list of probabilities, the second a list of variables); returns a sample from a categorical distribution. Note: categorical will renormalize a list of numbers into a list of probabilities

categorical({ps:[1,2,3],vs:["a","b","c"]})

//categorical([1,2,3],["a","b","c"])
