Creation of the RunOptions object required to the RunModel functions.

\details{
Users wanting to use \code{FUN_MOD} functions that are not included in 
the package must create their own \code{RunOptions} object accordingly.

##### Initialisation options #####

The model initialisation options can either be set to a default configuration or be defined by the user.

This is done via three vectors: \cr \code{IndPeriod_WarmUp}, \code{IniStates}, \code{IniResLevels}. \cr
A default configuration is used for initialisation if these vectors are not defined.

(1) Default initialisation options:

\itemize{
\item \code{IndPeriod_WarmUp} default setting ensures a one-year warm-up using the time steps preceding the \code{IndPeriod_Run}. 
The actual length of this warm-up might be shorter depending on data availability (no missing value of climate inputs being allowed in model input series).

\item \code{IniStates} and \code{IniResLevels} are automatically set to initialise all the model states at 0, except for the production and routing stores which are respectively initialised at 30 \% and 50 \% of their capacity. In case GR6J is used, the exponential store is initialised by default with 0 mm. This initialisation is made at the very beginning of the model call (i.e. at the beginning of \code{IndPeriod_WarmUp} or at the beginning of \code{IndPeriod_Run} if the warm-up period is disabled).
}

(2) Customisation of initialisation options:

\itemize{
\item \code{IndPeriod_WarmUp} can be used to specify the indices of the warm-up period (within the time-series prepared in InputsModel). \cr
- remark 1:	for most common cases, indices corresponding to one or several years preceding \code{IndPeriod_Run} are used (e.g. \code{IndPeriod_WarmUp = 1000:1365} and \code{IndPeriod_Run = 1366:5000)}. \cr
However, it is also possible to perform a long-term initialisation if other indices than the warm-up ones are set in \code{IndPeriod_WarmUp} (e.g. \code{IndPeriod_WarmUp <- c(1:5000 , 1:5000 , 1:5000 , 1000:1365)}). \cr
- remark 2:	it is also possible to completely disable the warm-up period when using \code{IndPeriod_WarmUp = 0L}. This is necessary if you want \code{IniStates} and / or \code{IniResLevels} to be the actual initial values of the model variables from your simulation (e.g. to perform a forecast form a given initial state). 

\item \code{IniStates} and \code{IniResLevels} can be used to specify the initial model states. \cr
- remark 1: \code{IniStates} and \code{IniResLevels} can not be used with GR1A. \cr
- remark 2:	\code{IniStates} can be set to the \code{$StateEnd} output of a previous \code{RunModel} call. \cr
- remark 3:	if \code{IniStates} is used, all model states must be provided:
  \itemize{
  \item 7 values: production store level [mm], routing store level [mm], exponential store level [mm] (only with GR6J, 0 otherwise), and the 4 other values have to be set to 0;
  \item 60 floats [mm] are required for GR4J, GR5J and GR6J; 60+2*NLayers floats [mm] are required for \code{CemaNeigeGR4J}, \code{CemaNeigeGR5J} and \emph{CemaNeigeGR6J}; see fortran source code for details).
  }
- remark 4:	in addition to \code{IniStates}, \code{IniResLevels} allows to set the filling rate of the production and routing stores for the GR models. For instance for GR4J, GR5J and GR6J: \code{IniResLevels <- c(0.3, 0.5)} should be used to obtain initial fillings of 30\% and 50\% for the production and routing stores, respectively. \code{IniResLevels} is optional and can only be used if \code{IniStates} is also defined (the state values corresponding to these two stores in \code{IniStates} are not used in such case). \cr \cr
