### _collectEntries(any data, function transform) : struct ###

collect data from an array, struct or query into a new struct. The transform function can return either a Map, with a single key to be used as the key, and a 2nd level struct, or an array, where the 1st index in the key, and the 2nd is the value.

### _groupBy(any data, function grouping) : struct ###

Take an array/struct and group the data into a grouped struct. The closure should return the key that the data should be grouped by. For arrays, this will return a struct of arrays. For structs, this will return a struct of structures.

### _unique(any data, [function comparator]) : any ###

Returns an array with all the duplicates removed (i.e. unique). For structs, this iterates through all the values, and returns an array from that, with duplicates removed.

### _curry(function func, array args) : function ###

Curry a function from left to right. Currying is creating a wrapper function where you set a constant value for one or more of the arguments of the function being wrapped. If you curry the function: `function (a,b)` with values `[5]`, then your wrapper will accept one argument (b), and always pass 5 for a.

Run the closure in a thread. Must be run inside a _withPool() block to set up the ExecutorService, and close it off at the end.

This function allows you to share the underlying ExecutorService with multiple concurrent methods.<br/> For example, this shares a threadpool of 10 threads across multiple _eachParrallel calls:<br/> _withPool( 10, function() {<br/> _eachParrallel(array, function() { ... });<br/> _eachParrallel(array, function() { ... });<br/> _eachParrallel(array, function() { ... });<br/> });
