Homogenize the error bars for X-axis in log scale.

errorbarlogx turns the X-axis of the current error bar plot to log 
scale, and homogonizes the length of the horizontal segements which 
terminate the vertical error bars. 
By default, Matlab's ERRORBAR draws vertical error bars which are 
terminated by small horizontal segments of uniform length for the X- 
axis in linear scale. But when turning the X-axis to log scale, these 
segments become uneven. Using errorbarlogx makes them uniform again. 
errorbarlogx(N) specifies the relative length of the horizontal 
segments, normalized with the total range of the data. By default, 
N=0.01 is used. 
Limitations: errorbarlogx acts only on the last drawn curve. If this 
curve is not an error bar plot, it won't work.
