[docu] Tags for the TimeDependenteterogeneousParameter.

Documentation/ProjectFile/prj/parameters/parameter/TimeDependentHeterogeneousParameter/time_series/i_time_series.md

+Contains time series information. Each entry consists of a pair of time and
+parameter name. Values of the parameter are piecewise linear interpolated.

Documentation/ProjectFile/prj/parameters/parameter/TimeDependentHeterogeneousParameter/time_series/pair/i_pair.md

+Contains pair of time and parameter name.

Documentation/ProjectFile/prj/parameters/parameter/TimeDependentHeterogeneousParameter/time_series/pair/t_parameter_name.md

+Specification of the parameter name. The specified parameter have to be time
+independent, i.e., it must neither be a CurvedParameter nor a
+TimeDependentHeterogeneousParameter.

Documentation/ProjectFile/prj/parameters/parameter/TimeDependentHeterogeneousParameter/time_series/pair/t_time.md

+Specification of point in time in the time-parameter-name relation.
