sv register location to lazy-load handler when requested.
custom hashes may be registered via :func:`register_crypt_handler`,
or they may be registered by this function,
which will delay actually importing and loading the handler
until a call to :func:`get_crypt_handler` is made for the specified name.
:arg name: name of handler
:arg path: module import path
the specified module path should contain a password hash handler
called :samp:`{name}`, or the path may contain a colon,
specifying the module and module attribute to use.
for example, the following would cause ``get_handler("myhash")`` to look
for a class named ``myhash`` within the ``myapp.helpers`` module::
>>> from passlib.registry import registry_crypt_handler_path
>>> registry_crypt_handler_path("myhash", "myapp.helpers")
...while this form would cause ``get_handler("myhash")`` to look
for a class name ``MyHash`` within the ``myapp.helpers`` module::
>>> from passlib.registry import registry_crypt_handler_path
>>> registry_crypt_handler_path("myhash", "myapp.helpers:MyHash")
