call:

linfitplot(x, y, markerColor, lineColor, printRhoR2)

Given two vectors 'x' and 'y', the function compute and plot the linear fit, with the Correlation
Coefficient (Rho) between 'x' and 'y' and the Coefficient of Determination (R^2, "how much knowing
x it is possible to determine y").

Note: This function calls 'linfit.m'

INPUT

x : independent variable
y : dependent variable
markerColor : a string ('r', 'b' , 'none', ...) or [1 0 0], [0 0.5 0] ...
lineColor : a string ('r', 'b' , 'none', ...) or [1 0 0], [0 0.5 0] ...
printRhoR2 : if 1, print the Rho and R2 values

note: 'markerColor' and 'lineColor' can be left empty [].
in this case they will take the default values (black).
