report_mig_char-class: Migration report along with quantitative and qualitative characteristics

Description

Migration along with qualitative or quantitative characteristics or both (e.g.) weight of eels according to the size class per period of time, weight of fish according to gender, number of fish per age class. This class does not split migration evenly over time period. So, unlike calculations made in class report_mig and report_mig_mult the whole time span of the migration operation is not considered, only the date of beginning of the operation is used to perform calculations.

Objects from the Class

Objects can be created by calls of the form new('report_mig_char', ...). they are loaded by the interface using interface_report_mig_char function.
