usage: xflat2d_rgb [-h]

Displays animations of two dimensional binary lattices colored with 
arbirtary RGB values.

xflat2d_rgb expects the following formated input on standard input:

<nx> <ny>                                     ! Dimensions of lattice
<t>                                           ! FIRST display time
<val(1,1)>   <R(1,1)>   <G(1,1)>   <B(1,1)>   ! Lat, RBG values for site (1,1)
<val(2,1)>   <R(2,1)>   <G(2,1)>   <B(2,1)>   ! Lat, RBG values for site (2,1)
                     .
                     .
<val(nx,1)>  <R(nx,1)>  <G(nx,1)>  <B(nx,1)>  ! Lat, RBG values for site (nx,1)
<val(1,2)>   <R(1,2)>   <G(1,2)>   <B(1,2)>   ! Lat, RBG values for site (1,2)
                     .
                     .
<val(nx,2)>  <R(nx,2)>  <G(nx,2)>  <B(nx,2)>  ! Lat, RBG values for site (nx,2)
                     .
                     .
                     .
                     .
<val(1,ny)>  <R(1,ny)>  <G(1,ny)>  <B(1,ny)>  ! Lat, RBG values for site (1,ny)
                     .
                     .
<val(nx,ny)> <R(nx,ny)> <G(nx,ny)> <B(nx,ny)> ! Lat, RBG values for site (nx,ny)
<t>                                           ! SECOND input time
<val(1,1)>   <R(1,1)>   <G(1,1)>   <B(1,1)>   ! Lat, RBG values for site (1,1)
<val(2,1)>   <R(2,1)>   <G(2,1)>   <B(2,1)>   ! Lat, RBG values for site (2,1)
                     .
                     .
                     .

All inputs should be doubles (floats), except for the lattice dimensions
<nx> and <ny> which MUST be integers.

RBG values must be in the range 0.0 .. 1.0
RBG values less than 0.0 will be set to 0.0
RBG values greater than 1.0 will be set to 1.0

Lattice positions (1,1) and (nx,ny) correspond to the upper left and 
lower right positions of the display area respectively. 

Input is stream oriented so carriage returns are effectively ignored. 
Thus for example, the lattice values at a given time could appear on 
a single line, one per line, one row per line etc.
