Detailed Description

Class for defining combinations of fit parameter objects.

Allows for combinations of LauParameters to be passed to the fit models. Equations of the form [0]*2 + 3*[1] are accepted, with a vector of LauParameters to define inputs [0] and [1]. The parameter for [0] must be stored first in the vector, and so on.
