//! \brief Unit attribute Function set. 
/*!
  MFnUnitAttribute is the function set for dependency nodes attributes
  that store one of the fundamental types of Maya data.  The currently
  supported types are MAngle, MDistance, and MTime.

  It is possible to set the defaults using a double.  This is valid
  for angles and distances.  In the case of angles, the value is
  assumed to be in radians, and in the case of distances, it is
  assumed to be in centimeters.  Time values should not be set using a
  double.

  It is possible to use unit attributes in place of double attributes
  when creating numeric compounds (see MFnNumericAttrbute).  To create
  a numeric compound of three distance values, create the three child
  attributes using MFnUnitAttribute and then pass the children into
  the create method of MFnNumericAttribute.
