DWBGenerator_FIZ: Collect decay, waste and breakage factor in FIZ routine
In bcgov/BCForestGroundSample: BC forest ground sample compilation

Description Usage Arguments Value Author(s)

This function is to collect the dead, waste and breakage factor from lookup table and join them into tree data. Instead of reading the lookup table from disk, the function uses hard-coded the lookup table. This function is equivalent to second part of dwb_fct.sas macro. For BEC routine, the decay, waste and breakage are collected using funtion DWBGenerator_BEC

DWBGenerator_FIZ(DBHClass, tabNumber, riskGroup)

## S4 method for signature 'numeric,character,character'
DWBGenerator_FIZ(DBHClass,
  tabNumber, riskGroup)

`DBHClass`	numeric, Tree DBH class. Currently, The function is capatable to the DBH class with 5 cm interval. It can be derived using `DBHClassifier`.
`tabNumber`	character, This character consist of 4 numbers. The first two number is the species number, and the last is the series number.
`riskGroup`	character, Specifies the risk group. It must be one of `1`, `2` or `3`. It can be derived from `riskGroupDeriver`.
