Parameters

The SEP.args.basic object can be thought of as a collection of parameters accessible using SEP programming conventions. You can request a parameter using par.par("tag"), optionally with a default value, and an error if it doesn't exist. You can also add a parameter par.add_param("tag",value) to the collection. The SEP.args.basic can be initialized from a file, another collection of parameters, or an empty set can be created. It has the ability to output its contents in various manners. For example, it can return a simple dictionary linking parameters to their values or can return the parameters in a sep-style convention (par=val) in either a list or string form. It can also write its contents into a file.
