/**
* This isn't just the name of an input, it's a path pointing to an input. The
* path is similar to a folder path: slash (/) means to descend into a subsection,
* dot-dot-slash (../) means to ascend into the parent section.
* After a series of slashes and dot-dot-slashes, there should be the name of an input,
* which will be returned.
* Eg, if you want the related input to be conditional on a sibling input name 'foobar'
* just use 'foobar'. If you want it to be conditional on an aunt/uncle input name
* 'baz', use '../baz'. If you want it to be conditional on a cousin input,
* the child of 'baz_section' named 'baz_child', use '../baz_section/baz_child'.
* Etc
* @param string|false $form_section_path we accept false also because substr( '../', '../' ) = false
* @return EE_Form_Section_Base
