``parameter``
=============
This module contains a set of factory functions for setting up the
observation models, for use in the tudat estimation framework

This module and its constituents are in many cases documented under the assumption that its functionalities are used in the context of an estimation problem.
However, since estimatable parameter settings are firstly used to set up variational equations of the dynamical / observation model w.r.t. the estimatable parameters,
the functionality of this module can be relevant in any context in which variational equations are required.
