Add Documentation

[abnowack]

Most classes, methods, functions do not have any docstrings for documentation.
PEP 0257 describes the standard format

Single line

def kos_root():
    """Return the pathname of the KOS root directory."""

Multi-Line

def complex(real=0.0, imag=0.0):
    """Form a complex number.

    Keyword arguments:
    real -- the real part (default 0.0)
    imag -- the imaginary part (default 0.0)
    """
    if imag == 0.0 and real == 0.0:
        return complex_zero

Several formats are available which describe what text to write (args, return values, descriptions)
Most popular are

• Numpydoc format
  • Example
  • Example
• Google style guide format
  • Example

Additionally meta text format specifiers are also used, such as Markdown and reStructuredText (reST)
Sphinx is a common documentation generator and uses reST. In general reST is more popular than Markdown for python docstrings
