	* Add static method to Doc to allow merging of multiple docs. * Add error description for the error that occurs if docs with different vocabs (from different languages) are merged in Doc.from_docs(). * Add test for Doc.from_docs() implementation. * Fix using numpy's concatenate in Doc.from_docs. * Replace typing's type annotations in from_docs. * Simply remove type annotations in from_docs. * Add documentation for Doc.from_docs to api. * Simplify from_docs, its test and the api doc for codebase consistency. * Fix merging of Doc objects that end with whitespaces (Achieved by simply not setting the SPACY attribute on whitespace tokens). Remove two unnecessary imports of attributes. * Add merging of user data from Doc objects in from_docs. Add user data test case to corresponding test. Add applicable warning messages. * Fix incorrect setting of tokens idx by using concatenated spaces (again). Add test case to corresponding test. * Add MORPH to attrs * Update warnings calls * Remove out-dated error from merge * Rename space_delimiter to ensure_whitespace Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com>
