Add table calculator filter that takes a table, an expression and a column name as input and uses the expression to extract columns from the input table, and create a new column with values created by executing the expression on each row of the table.
For example:
a*(b+c) would look for columns named 'a', 'b' and 'c' and perform the expression on each one of the set of row values, creating a new column value with the results.
The 'calc' branch contains a draft implementation of this filter.
