solution of one compartmental oral administration model only use one set of parameters, times can input can be an numeric array
oneCompartmentOralModel(parameters, time, dosingInfo)a numeric verctor of parameters as input to the model with names
Ka: constant absorption rate
Ke: constant elimination rate
dose: initial dose
volume: volume to which the dose is administered
a numeric vector containing timePoints at which the concentration should be predicted timepoint zero is defined as the moment the dose is administered
see link{PkModel-class} but opnly one dose at time zero allowed
vector of concentrations corresponding to the input timePoints
