class RooTruthModel: public RooResolutionModel

 Constructor of a truth resolution model, i.e. a delta function in observable 'xIn'

 Copy constructor

 Destructor

 Return basis code for given basis definition string. Return special
 codes for 'known' bases for which compiled definition exists. Return
 generic bases code if implementation relies on TFormula interpretation
 of basis name

 Changes associated bases function to 'inBasis'

 Evaluate the truth model: a delta function when used as PDF,
 the basis function itself, when convoluted with a basis function.

 Advertise analytical integrals for compiled basis functions and when used
 as p.d.f without basis function.

 Implement analytical integrals when used as p.d.f and for compiled
 basis functions.

 Advertise internal generator for observable x

 Implement internal generator for observable x,
 x=0 for all events following definition
 of delta function
