Discrete

• - Binomial distribution (c: count, p: probability)
  - 'binom(c,p)'
  'binom(3, 0.25)'

• - Histogram of an arbitrary discrete distribution (c: value)
  - 'hist(c*:p,*)'
  'hist( 3.1, 5.3, 4.2 : 0.6 , 0.2, 0.2 )'

• - distribution over a single point (c: value)
  - 'delta(c)'
  'delta(3.14)'
