Details:

Currently MakeProfiles has a special 'radial' profile for putting the radius
of each pixel compared to a given center. This can be used to build any
arbitrary radial profile with a custom program. 

But to make things simple for the users, it would be good if the user could
give a table as input and MakeProfiles would look at that table to put the
respective values in the built profile.

The table would have three columns with the first two identifying the interval
and the third identifying the value. For example this table:


# Column 1: Lower [pixels,f64] Interval's lower-limit (inclusive)
# Column 2: Larger [pixels,f64] Intervals larger-limit (exclusive)
# Column 3: Value [arbitrary,f64] Value to use for pixels in this interval
0.0   0.5      1
0.5   1.0      2
1.0   1.5      3
1.5   2.0      4
2.0   2.5      5
2.5   3.0      6


MakeProfiles will then accept this table as a value to a new option, like
'--radial-profile'. When reaching a 'radial' profile, it will use the values
given in this table to fill the profile. For example like this:


astmkprof catalog.fits --radial-profile=profile.txt


An alternative may be to allow a file name in the actual input catalog instead
of a raw 'radial' profile. When it is confronted, MakeProfiles will assume its
a table and open it for using as profile values. This second proposal is more
general and can allow many profiles in one final image.
