  This is handled by using a reference counting mechanism. Whenever somebody copies a header of a
  *Mat* object, a counter is increased for the matrix. Whenever a header is cleaned, this counter
  is decreased. When the counter reaches zero the matrix is freed. Sometimes you will want to copy

  Each of the building components has its own valid domains. This leads to the data type used. How
  we store a component defines the control we have over its domain. The smallest data type possible is
