Add Do's and Don't

[kdayday]

Especially with time-series access

Will need examples from @jd-lara and @daniel-thom

[jd-lara]

Dont's preliminary list to be documented

• Modify the system in place
• add/remove time series in place within an algorithm

[jd-lara]

Note to myself add a don't based on #1386 about vectorized operations

Hi @jd-lara, it seems that the internal code use PowerNetworkMatrices? Could you give a minimal example to better extract and create something similar to DataFrame to pass to other solver/program? Thank you. This really helps.

My approach is really bad because I'm not yet familiar with both Sienna and Julia. But it currently works fast anyway due to extremely small case. Willing to learn here :muscle:.
