This is the place where the blocks are defined. All blocks inherent bas Block class from _block.py and implement the specific methods for the block behavior. The blocks are grouped thematically into modules. Standard blocks can be imported directly from the block library like this:

from pathsim.blocks import Adder, Amplifier

Or from the respective module:

from pathsim.blocks.adder import Adder
from pathsim.blockd.amplifier import Amplifier

The goal is to keep the available blocks that can be imported direcly general purpose and have separate toolboxes for special purpose blocks. For example for different domains such as chemical engineering, or robotics.
