Tabular representation of a parameter mapping.

With columns corresponding to the parameter names of a naive Monod process model, the parametrization of each replicate, identified by a replicate ID (rid) is specified in a tabular format. Parameter identifiers that appear multiple times (e.g. S0) correspond to a parameter shared across replicates. Accordingly, replicate-local parameters names simply do not appear multiple times (e.g. X0_A06). Numeric entries are interpreted as fixed values and will be left out of parameter estimation. Columns do not need to be homogeneously fixed/shared/local, but parameters can only be shared within the same column. The parameter mapping can be provided as a DataFrame object.
