Functions that are used by the Gecros sim components.
Handles tabulated values (X and Y column) and returns for a x-value
a y-value by using the table (lookup, interpolation etc.)
Calculates effective temperature sums for anthesis and maturity based on daily temperature and base temperatures
WIKI_START
== Daily rates of temperature sums ==
The model takes daily mean temperature `iAirTemperatureMean` and the parameters
`cBaseTempBeforeAnt` and `cBaseTempAfterAnt` and calculates the coresponding
`EffectiveTempRateBeforeAnt` and `EffectiveTempRateAfterAnt` by subtracting the base temperatures
from the mean temperatures.
Texture Class Functions are developed to determine soil hydraulic properties e.g. total porosity,
residual water, field capacity, permanent wilting point, saturated hydraulic conductivity, ALPHA, and N
for different soil texture classes based on USDA soil texture classification.
