Formula that takes the modelled volume of a bivalve shell by
 sub-increment and calculates mass increase using variable shell density.

Contains all the formulae of the growth and trace element uptake model described in the equally-named
Geoscientific Model Development paper (de Winter, 2017, <doi:10.5194/gmd-2017-137>). The model takes as input a file with X- and Y-coordinates of digitized
growth increments recognized on a longitudinal cross section through the bivalve shell, as well as a BMP file of an elemental map of the
cross section surface with chemically distinct phases separated by phase analysis. It proceeds by a step-by-step process described in
the paper, by which digitized growth increments are used to calculate changes in shell height, shell thickness, shell volume, shell mass
and shell growth rate through the bivalve's life time. Then, results of this growth modelling are combined with the trace element mapping
results to trace the incorporation of trace elements into the bivalve shell. Results of various modelling parameters can be exported in
the form of XLSX files.
