Two Tsv Strings, Compare Numeric Cells

// (c) 2020, Questetra, Inc. (the MIT License)
// Notes:
// Search for lines with the Key and compare the numeric cells.
// Assumes a digit separator and evaluates all numbers after removing all commas ",".
// {Growth Value} and {Growth Rate} are calculated. 
// "Infinity" is output for the zero denominator.
// Value Rate and the values of the specified B column IDs are output in TSV.
// {Growth Value} {Growth Rate} {B-Column0} {B-Column1}... 
// 
// Notes(ja):
// 同一Keyの行を探索し、数値セル同士を比較します。
// 桁区切り文字を想定し、全てのカンマ “,” を除去したうえで数値判定します
// {増加値}と{増加率}が算出されます。
// 　ゼロ分母は "Infinity" が出力されます。
// {増加値} {増加率} および指定したBカラムIDの値がTSV出力されます。
// 　{増加値} {増加率} {B-Column0} {B-Column1}...
