def find_executable(name):
    """
    Returns the path of an executable file.

    Searches for an executable with the given name, first in the `PATH`, 
    then in the current directory (recursively). Upon finding the file,
    returns the full filepath of it.

    Parameters
    ----------
    name : str
        The name of the executable. This is platform-independent so 
        you don't have to include any platform-specific file extension 
        (such as `.exe`).

    Returns
    -------
    str
        The path of the executable file. In case of multiple hits, it 
        only returns the first one.
