Update all docstrings to be ReadTheDocs compatible and fill in missing docstrings

[isaacmg]

ReadTheDocs requires docstrings to have an additional newline between the header and the parameters if strings are not in this format it will not render properly. Therefore we want to put all docstrings into the following format

def some_function(a_number: int, a_string: str) -> str:
    """
    A function that concatenates a string to 

    :param a_number:  A number that ....
     :type a_number: int
     :param a_string: Some string that does something
     :type  a_string: str 
      :return: A concatenated integer with s
      :rtype: str
    """
   return str(a_number) + a_string 

They should all have a heading describing the functionality and then have a new line then all the parameters. This will help users use our documentation and make things easier.
