A few changes to make the 'residue.create()' user function partially functional.

Added an import statement for the 'residue' module of the 'generic_fns' package.

Removed the 'self' argument to the create() function.

Converted the Residue.create() method into a function of the 'generic_fns.residue' module.

Created the 'generic_fns.residue' module and started converting the sequence add() fn to create().

Added initial support for the residue user function class.

The file 'prompt/residue.py' was copied from 'prompt/sequence.py' and the function 'add()' renamed
to 'create' (generating the 'residue.create()' user function). All the other sequence user
functions still remain unchanged.
