named values to be included in return value

startdate: start date of the simulation.
enddate: end date of the simulation.
fornetrad: use global solar radiation (="globrad") or sunshine duration hours (="sunhour") for net radiation calculation?
prec.interval: number of precipitation intervals per day (default is 1). If prec.interval > 1, a separate file ("in/PRFILE.DAT") has to be provided manually!
richter.prec.corr: correct precipitation data for wind and evaporation losses (not implented yet)
budburst.method: name of method for budburst calculation. If 'constant' or 'fixed', budburst day of year from parameters is used. All other methods calculate budburst day of year dynamically from temperatures, and the method name is passed to the 'start.method'-argument of vegperiod.
leaffall.method: name of method for leaffall calculation. If 'constant' or 'fixed', beginning of leaffall (day of year) from parameters is used. All other methods calculate budburst day of year dynamically from temperatures, and the method name is passed to the 'end.method'-argument of vegperiod.
standprop.input: name of input for longterm (interannual) plant development. 'parameters': yearly values of stand properties height, sai, densef, lai come from parameters, 'table': values come from a table, see 'longtermdev'-argument of Run.B90.
standprop.interp: interpolation method for aboveground stand properties. 'linear' or 'constant', see 'approx.method'-argument of approx_standprop.
standprop.use_growthperiod: Should yearly changes of stand properties (growth) only take place during the growth period? If TRUE, linear interpolation of height, sai, densef and age are made from budburst until leaffall. During winter values are constant. Beginning and end of the growth period are taken from parameters budburstdoy and leaffalldoy. See 'use_growthperiod'-argument of approx_standprop.
lai.method: name of method for constructing seasonal course leaf area index development from parameters. Passed to 'method'-argument of MakeSeasLAI.
imodel: name of hydraulic parameterization: "CH" for Clapp/Hornberger, "MvG" for Mualem/van Genuchten
root.method: method name of the root length density depth distribution function. Any of the names accepted by MakeRelRootDens are allowed. Additionally, "soilvar" can be used if the root length density depth distribution is specified in column 'rootden' in the soil-data.frame

Returns a list of default model control options for use as 'options.b90'-argument in Run.B90.
