* ProcessWire Modules
*
* Loads and manages all runtime modules for ProcessWire
*
* Note that when iterating, find(), or calling any other method that returns module(s), excepting get(), a ModulePlaceholder may be
* returned rather than a real Module. ModulePlaceholders are used in instances when the module may or may not be needed at runtime
* in order to save resources. As a result, anything iterating through these Modules should check to make sure it's not a ModulePlaceholder
* before using it. If it's a ModulePlaceholder, then the real Module can be instantiated/retrieved by $modules->get($className).

* ### Return value details
*
* #### If module is configurable via external configuration file:
*
* - Returns string of full path/filename to `ModuleName.config.php` file
*
* #### If module is configurable because it implements a configurable module interface:
*
* - Returns boolean `true` if module is configurable via the static `getModuleConfigInputfields()` method.
* This particular method is compatible with all past versions of ProcessWire.
* - Returns integer `2` if module is configurable via the non-static `getModuleConfigInputfields()` and requires no arguments.
* - Returns integer `3` if module is configurable via the non-static `getModuleConfigInputfields()` and requires `$data` array.
* - Returns integer `4` if module is configurable via the non-static `getModuleConfigInputfields()` and requires `InputfieldWrapper` argument.
* - Returns integer `19` if module is configurable via non-static `getModuleConfigArray()` method.
* - Returns integer `20` if module is configurable via static `getModuleConfigArray()` method.
*
* #### If module is not configurable:
*
* - Returns boolean `false` if not configurable
*
* *This method is named isConfigurableModule() in ProcessWire versions prior to to 3.0.16.*
*
* #pw-group-configuration
*
* @param Module|string $class Module name
* @param bool $useCache Use caching? This accepts a few options:
* - Specify boolean `true` to allow use of cache when available (default behavior).
* - Specify boolean `false` to disable retrieval of this property from getModuleInfo (forces a new check).
* - Specify string `interface` to check only if module implements ConfigurableModule interface.
* - Specify string `file` to check only if module has a separate configuration class/file.
* @return bool|string|int See details about return values in method description.
* @since 3.0.16
*
* @todo all ConfigurableModule methods need to be split out into their own class (ConfigurableModules?)
* @todo this method has two distinct parts (file and interface) that need to be split in two methods.
