/**
 * it is not uncommon for non-english speaking countries to use a comma for a
 * decimal place. this sorting plug-in shows how that can be taken account of in
 * sorting by adding the type `numeric-comma` to datatables. a type detection 
 * plug-in for this sorting method is provided below.
 * 
 * please note that the 'formatted numbers' type detection and sorting plug-ins
 * offer greater flexibility that this plug-in and should be used in preference
 * to this method.
 *
 *  @name commas for decimal place
 *  @summary sort numbers correctly which use a comma as the decimal place.
