The user can take any gamlss.family and create a truncated version of it. Left,
right and both sides truncation is allowed.
For continuous distributions left truncation at 3 means that the random variable can take the value 3.
For discrete distributions left truncation at 3 means that the random variable can take values from 4 onwards.
This is the same for right truncation. Truncation at 15 for a discrete variable means that
15 and greater values are not allowed but for continuous variable it mean values greater that 15 are not allowed
(so 15 is a possible value).
