TSV String, Filter by Numeric

// (c) 2019, Questetra, Inc. (the MIT License)
// Notes:
// Numeric parsing depends on JavaScript parseFloat().
// If a "prefix" precedes a number, it will not be determined as a number. (eg "$ 100")
// The period "." is recognized as a decimal point.
// Assumes a digit separator and evaluates all numbers after removing all commas ",".
// If infinity, specify "(-)Infinity". (eg. "-Infinity<36.4,37.5<Infinity")
// For "AND search", try to place this Automated Step serially.
// Equals at range boundary values are included. (No Problem "37.0<37.0")
//
// Notes(ja):
// 数値判定は JavaScript parseFloat() に依存します
// 数値の前に "接頭辞" があると数値として判定されません ( 例 "$100" )
// ピリオド "." は小数点として認識されます
// 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
// 無限大は "(-)Infinity" を指定します （例 "-Infinity<36.4,37.5<Infinity"）
// "AND検索" は自動工程の直列配置をお試しください
// 範囲境界値はフィルタ範囲に含まれます （問題のない設定例 "37.0<37.0"）
