const char *name()
    Purpose: get the id name of the object
    Input Arguments: None
    Return Value: the id name stored in the object.
    Notes: if no name is set, NULL will be returned
            the id name is used to identify this object from
            all other objects and should be unique
    Code Example:

void name(const char *val)
    Purpose: set the id name of the object
    Input Arguments: 1
        1. const char *val - new id name
    Return Value: None
    Notes: a copy of the memory location val will be stored
    Code Example:

const char *path()
    Purpose: get the path of the object
    Input Arguments: None
    Return Value: the path stored in the object.
    Notes: if no path is set, NULL will be returned
            the path tells where this object sits in the
            hierarchy of objects.
    Code Example:

void path(const char *val)
    Purpose: set the path of the object
    Input Arguments: 1
        1. const char *val - new path
    Return Value: None
    Notes: a copy of the memory location val will be stored
    Code Example:

const char *label()
    Purpose: get the label of the object
    Input Arguments: None
    Return Value: the label stored in the object.
    Notes: if no label is set, NULL will be returned
            the label is used by the graphical user interface.
    Code Example:

void label(const char *val)
    Purpose: set the label of the object
    Input Arguments: 1
        1. const char *val - new label
    Return Value: None
    Notes: a copy of the memory location val will be stored

const char *desc()
    Purpose: get the description of the object
    Input Arguments: None
    Return Value: the description stored in the object.
    Notes: if no description is set, NULL will be returned
            the description is used by the graphical user
            interface to describe what type of data is being
            requested and how the input is used.
    Code Example:

void desc(const char *val)
    Purpose: set the description of the object
    Input Arguments: 1
        1. const char *val - new description
    Return Value: None
    Notes: a copy of the memory location val will be stored
    Code Example:

const char *hints()

            the hints are used by the graphical user interface
    Code Example:

void hints(const char *val)
    Purpose: set the hints of the object
    Input Arguments: 1
        1. const char *val - new hints
    Return Value: None
    Notes: a copy of the memory location val will be stored
    Code Example:

        5. const char *scale - scale of axis
        6. const double *val - array of data values as doubles
        7. size_t size - number of data values
    Return Value: pointer to newly created Array1D object
    Notes: valid options for scale are "log" and NULL. The newly
           created Array1D object is stored in the Curve object.
    Code Example:

Curve& delAxis(const char *name);
