! PARAMETERIZE_ARC_LENGTH parameterizes data by pseudo-arclength.
Discussion:
A parameterization is required for the interpolation.
This routine provides a parameterization by computing the
pseudo-arclength of the data, that is, the Euclidean distance
between successive points.

Parameters:
Input, integer ( kind = 4 ) DIM_NUM, the spatial dimension.
Input, integer ( kind = 4 ) DATA_NUM, the number of data points.
Input, real ( kind = 8 ) P_DATA(DIM_NUM,DATA_NUM), the data values.
Output, real ( kind = 8 ) T_DATA(DATA_NUM), parameter values
assigned to the data.
