Create page on "defining new ComponentTypes using LEMS" about documentation

[pgleeson]

A script for building LEMS with Python: https://github.com/LEMS/pylems/blob/master/examples/apitest2.py
Defining a completely new (non neuro) type in XML: https://github.com/NeuroML/NeuroMLlite/blob/master/examples/test_files/Lorenz1963.xml
Defining a new synapse in LEMS: https://github.com/OpenSourceBrain/BonoClopath2017/blob/master/NeuroML2/AMPA_NMDA.synapse.nml
Defining a new LEMS channel (or more specificly a gate ina channel): https://github.com/OpenSourceBrain/SmithEtAl2013-L23DendriticSpikes/blob/master/NeuroML2/na.channel.nml
Defining a new calcium pool (concentrationModel) in LEMS: https://github.com/OpenSourceBrain/PospischilEtAl2008/blob/master/NeuroML2/channels/Ca/Ca.nml

Need an example of creating a LEMS type in Python, but building on the baseCell, baseSynapse, etc.
