 called the motor pool. The brain essentially says "activate 30% of the
 motor pool" and the spinal cord recruits motor neurons untill 30% are
 activated. Since the distribution of power among motor neurons is
-unequal and recruitment goes from weakest to strongest, 30% of the
-motor pool might be 5% of the strength of the muscle.

 My simulated muscles follow a similiar design: Each muscle is defined
-by a 1-D array of numbers (the "motor pool"). Each number represents a
-motor neuron which controlls a number of sarcomeres equal to the
-number. A muscle also has a scalar :strength factor which determines
-the total force the muscle can exert when all motor neurons are
-activated.  The effector function for a muscle takes a number to index
-into the motor pool, and that number "activates" all the motor neurons
-whose index is lower or equal to the number.  Each motor-neuron will
-apply force in proportion to its value in the array.  Lower values
-cause less force.  The lower values can be put at the "beginning" of
-the 1-D array to simulate the layout of actual human muscles, which
-are capable of more percise movements when exerting less force. Or,
-the motor pool can simulate more exoitic recruitment strageties which
-do not correspond to human muscles.

 This 1D array is defined in an image file for ease of
 creation/visualization. Here is an example muscle profile image.
