algor: The minimisation algorithm.
dir: The directory to place the files.
force: A flag which if set to True will cause the results file to be overwritten if it already exists.
The script file created is called `dir/dasha_script'.
The two minimisation algorithms within Dasha are accessible through the algorithm which can be set to:
For Levenberg-Marquardt minimisation, the function `lmin' will be called, while for Newton-Raphson, the function `min' will be executed.
