The FieldStrengthCellLibrary class provides a library scheme for grouping spatial cells based on radiation field strength.
The library contains a one-dimensional set of entries corresponding to different strengths of the stored radiation field, parameterized by the quantity
\[ U = \frac{ \int_0^\infty J_\lambda\, {\text{d}}\lambda }{ \int_0^\infty J_\lambda^{\text{MW}}\, {\text{d}}\lambda }, \]
where \(J_\lambda^{\text{MW}}\) is the the local interstellar radiation field in the Milky Way according to Mathis et al. (1983). The mapping from spatial cells to library entries is built dynamically from binning the \(N_{\text{cells}}\) values of \(U\) as calculated from the medium system onto a one-dimensional grid with a user-configurable number of field strength bins.
When an item of this type is used, the names provided by the conditional value expression "NonIdentitySpatialCellLibrary" are inserted into the name sets used for evaluating Boolean expressions.

Default constructor for concrete Item subclass FieldStrengthCellLibrary: "a library scheme for grouping spatial cells based on radiation field strength".
This function returns a vector nv with length \(N_{\text{cells}}\) that maps each cell index \(m\) to the corresponding library entry index \(n_m\). In this class the function loops over all spatial cells and calculates the strength \(U_m\) of the radiation field for each of them. Based on these values, a logarithmic grid in \(U\) embracing these values is established,
\[ U_{(n)} = U_{\text{min}} \left( \frac{ U_{\text{max}} }{ U_{\text{min}} } \right)^{n/N_U} \qquad n=0,\ldots,N_U, \]
where \(U_{\text{min}}\) and \(U_{\text{max}}\) represent the smallest and largest values of the field strength found among all cells. Then the function determines for each cell \(m\) the corresponding library entry \(n\).
Implements SpatialCellLibrary.

This function returns the value of the discoverable integer property numFieldStrengths: "the number of field strength bins".
The minimum value for this property is "10".
The maximum value for this property is "10000000".
The default value for this property is given by the conditional value expression "1000".
