weight_economic_value: Multiply Economic Values With A Weight Matrix
In pvrqualitasag/MeatValueIndex:

Compute the weighted factors based on an input tibble with unweighted economic values and a tibble with weighting factors. The two input tibbles must have the same dimensions. If the first column contains some names this is indicated with the parameter pb_first_col_trait_name and the first column is ignored for the computation x of the weighted factors. In the result the first column is added back in.

`ptbl_economic_value`	tibble with economic values
`ptbl_weight`	tibble containing weights
`pb_first_col_trait_name`	flag indicating wether first column are trait names
