 Non-standard lineshapes are used to model resonances that do not conform to a simple `BreitWigner` distributions, or a `MultichannelBreitWigner` has to be defined explicitly.
 The code below defines a new `NonResonant` lineshape, and its deserialization method. In this case this is just a constant.

-struct Constant <: HadronicLineshapes.AbstractFlexFunc

 ## Deserialization of Objects to a Workspace
 
 Model components are deserialized from a JSON file into computational objects within a workspace for further manipulation. First, functions representing lineshapes and form-factors are built. Following this, distributions are processed and added to the workspace.
