              Re-setting Data in MODEL_F90

Some iterative applications will require you to change the properties 
you have supplied.  The system allows for the input of integer (fixed)
and real (floating point) data for each node, and/or each element,
and/or miscellaneous global data.  (All of the properties are treated
in an object-oriented fashion in module Sys_Properties_Data. There the
dynamically allocated property arrays are stored as public attributes,
and the encapsulated functionality includes the routines to access and
modify the properties as cited below.)

Sometimes in iterative solutions you want to set new property values
by assigning a new VALUE to old property number.  Then call:
    SET_INTEGER_MISC (I, VALUE) for integer property number I
    SET_REAL_MISC    (R, VALUE) for real    property number R
    1 <= I <= integers (keyword value)
    1 <= R <= reals    (keyword value)
to set a single miscellaneous global data item, or

    SET_INTEGER_LP (IE, I, VALUE) for integer property number I
    SET_REAL_LP    (IE, R, VALUE) for real    property number R
    1 <= I  <= el_int   (keyword value)
    1 <= R  <= el_reals (keyword value)
    1 <= IE <= elems    (keyword value)
to set a single standard element data item, for element IE, or 

    SET_INTEGER_MX (IE, I, VALUE) for integer property number I
    SET_REAL_MX    (IE, R, VALUE) for real    property number R
    1 <= I  <= mixed_int   (keyword value)
    1 <= R  <= mixed_reals (keyword value)
    1 <= IE <= mixed_segs  (keyword value)
to set a single mixed element data item, for element IE, or 

    SET_INTEGER_SP (IE, I, VALUE) for integer property number I
    SET_REAL_SP    (IE, R, VALUE) for real    property number R
    1 <= I  <= seg_int   (keyword value)
    1 <= R  <= seg_reals (keyword value)
    1 <= IE <= segments  (keyword value)
to set a single mixed element data item, for element IE, or 

    SET_INTEGER_NP (IN, I, VALUE) for integer property number I
    SET_REAL_NP    (IN, R, VALUE) for real    property number R
    1 <= I  <= pt_int  (keyword value)
    1 <= R  <= pt_real (keyword value)
    1 <= IN <= nodes   (keyword value)
to set a single nodal data item, for node IN.
