pathGet($values, $path, $default = NULL)   X-Ref
Get a single value from an array-tree.

param: array     $values   Ex: ['foo' => ['bar' => 123]].
param: array     $path     Ex: ['foo', 'bar'].
param: mixed     $default
return: mixed               Ex 123.

pathIsset($values, $path)   X-Ref
Check if a key isset which may be several layers deep.

This is a helper for when the calling function does not know how many layers deep
the path array is so cannot easily check.

param: array $values
param: array $path
return: bool

pathSet(&$values, $pathParts, $value)   X-Ref
Set a single value in an array tree.

param: array   $values     Ex: ['foo' => ['bar' => 123]].
param: array   $pathParts  Ex: ['foo', 'bar'].
param: mixed   $value      Ex: 456.
return: void

recursiveIsset($array, $path)   X-Ref
Check if a key isset which may be several layers deep.

This is a helper for when the calling function does not know how many layers deep the
path array is so cannot easily check.

param: array $array
param: array $path
return: bool

recursiveValue($array, $path, $default = NULL)   X-Ref
Check if a key isset which may be several layers deep.

This is a helper for when the calling function does not know how many layers deep the
path array is so cannot easily check.

param: array   $array
param: array   $path       An array of keys,
param: mixed   $default    Value to return if not found.
return: bool

recursiveBuild($path, $value, $source = array()   X-Ref
Append the value to the array using the key provided.

e.g if value is 'llama' & path is [0, 'email', 'location'] result will be
[0 => ['email' => ['location' => 'llama']]

param: $path
param: $value
param: array   $source
return: array
