extends java.lang.Object
These are utilities that should exist elsewhere, but I can't find a good simple library for them, and they are stupid but necessary for certain things.

Filter theList (of Map) using fieldValues; if exclude=true remove matching items, else keep only matching items
Find all values of a named field in a nested Map containing fields, Maps, and Collections of Maps (Lists, etc)
Find a field value in a nested Map containing fields, Maps, and Collections of Maps (Lists, etc)
For a list of Map find the entry that best matches the fieldsByPriority Ordered Map; null field values in a Map in mapList match against any value but do not contribute to maximal match score, otherwise value for each field in fieldsByPriority must match for it to be a candidate.
Creates a single Map with fields from the passed in Map and all nested Maps (for Map and Collection of Map entry values)
Order list elements in place (modifies the list passed in), returns the list for convenience
Removes entries with a null value from the Map, returns the passed in Map for convenience (does not clone before removes!).
Returns Map with total, squaredTotal, count, average, stdDev, maximum; fieldName field in Maps must have type BigDecimal; if count of non-null fields is less than 2 returns null as cannot calculate a standard deviation
