FlowQuery groupBy operation to group arrays by EEL discriminator

Once upon a time I had a list of persons nodes, and I needed to group them by first letter. So I decided there should be a generic way to group array of nodes into subgroups, based on an EEL expression... And here it is!

TL;DR
-----

[](#tldr)

Install: `composer require dimaip/groupby`

Use:

```
groupedNodesByFirstLetterOfLastName = ${q(nodes).groupBy('String.substring(node.properties.lastName, 0, 1)')}

```

Full example
------------

[](#full-example)

Once you have grouped the nodes, you can render them any way you like: with Fluid (yikes!) or with Fusion (yay!).

```
prototype(Name.Space:GroupedList) < prototype(TYPO3.TypoScript:Collection) {
	@process.tmpl = ${'' + value + ''}
	@context.nodes = ${q(site).find('[instanceof Name.Space:Person]')}
	collection = ${nodes.groupBy('String.substring(node.properties.lastName, 0, 1)')}
	itemName = 'nodes'
	itemKey = 'firstLetter'
	itemRenderer = TYPO3.TypoScript:Collection {
		@process.tmpl = ${'' + firstLetter + '' + value + ''}
		collection = ${nodes}
		itemName = 'node'
		itemRenderer = ${'' + node.properties.firstName + ' ' + node.properties.lastName + ''}
	}
}

```

In a similar way you can group nodes based on a very complex EEL expressions, let your imagination fly!
