/**
* Method to setup the autoloaders for the Joomla Platform.
* Since the SPL autoloaders are called in a queue we will add our explicit
* class-registration based loader first, then fall back on the autoloader based on conventions.
* This will allow people to register a class in a specific location and override platform libraries
* as was previously possible.
*
* @param integer $caseStrategy An option to define the class finding strategy for the namespace loader
* depending on the namespace and class path case.
* The possible values are :
* JLoader::LOWER_CASE : The namespace can be either lower case or camel case and the path lower case.
* JLoader::NATURAL_CASE : The namespace case matches the path case.
* JLoader::MIXED_CASE : It regroups option 1 and option 2.
* @param boolean $enableNamespaces True to enable PHP namespace based class autoloading.
* @param boolean $enablePrefixes True to enable prefix based class loading (needed to auto load the Joomla core).
* @param boolean $enableClasses True to enable class map based class loading (needed to auto load the Joomla core).
*
* @return void
*
* @since 12.3
