documentation "Running EnergyPlus from Eppy" needs updating

[santoshphilip]

documentation of https://eppy.readthedocs.io/en/master/runningeplus.html is in the wrong order

• Make idf.run() work like EPLaunch
• should be before Running in parallel processes
• since Running in parallel processes uses EpLaunch

docs have been updated
