/**
 * Although DataTables' internal numeric sorting works no problem on negative
 * numbers, it does not accept positively signed numbers. This plug-in will
 * sort just such data numerically.

 *  @name Fully signed numbers sorting
 *  @summary Sort data numerically with a leading `+` symbol (as well as `-`).
