After not working on this project for a while, I came back to it for a couple major updates. All the updates are included on the repository here. Those features include:

• Your system can now have multiple batteries.
• Your system can have multiple voltage regulators connected to each battery.
• Your system can still, as before, have multiple threads running on each regulator (and each thread can have multiple components.
• The support for switching and linear regulators has been improved. Both have quiescent current included, and the switching regulator has a efficiency input.
• A few bugs were fixed, especially in the charging/discharging calculations.
• Each regulator has a maximum current, and the tool will warn you if your exceed that.
• There are helpful printing and plotting tools for each system you build.
• Two new examples are added: a low power device with a coin cell battery and no recharging and a multiple battery example which is more complicated and shows more capabilities.

For anyone estimating the power consumption or battery life of a system with multiple power modes , this tool is for you!
