SticsOnR: Manage STICS Simulations Running the Executable or JavaStics,

Running simulations with the 'STICS' crop model. Different ways of performing simulations are available and based on three use-cases: 1/ Calling 'JavaStics' command line to run simulations on given situations. 'JavaStics' handles text files generation from 'XML' files; 2/ Calling the model 'fortran' executable directly. Text files must be produced beforehand; and 3/ Calling the model 'fortran' executable through a wrapper. It can handle distributed runs over the machine CPUs and returns simulated output data. The wrapper also provides a concise manner for running simulations using custom parameter values and allows to chain simulations for successive situations.
