Problem definition, the top-level class holding all data necessary to solve
a problem.
It can be constructed from a :class:`ProblemConf` instance using
`ProblemDefinition.from_conf()` or directly from a problem
description file using `ProblemDefinition.from_conf_file()`
For interactive use, the constructor requires only the `equations`,
`nls` and `ls` keyword arguments.
