Display Variables Conveniently

Simple to use function for display

The dis() function helps to display variables for debugging easily and conveniently.
Keeping track of changing variables during loops can be tedious sometimes. This simple function helps to produce a display variables in a simple and appealing manner with more functionality than Matlab's disp() function.
Usage:
a = 1; b = 2;
dis( a, b );
a = 1
b = 2

- Use '\n' to generate new line
dis( a, '\n', b );
a = 1

b = 2

- Use of varname
dis( 'value of a', a );
value of a = 1

- Display vectors:
x = (0:4) * pi/4;
dis( x );
x = 0 0.785398 1.5708 2.35619 3.14159

You can mix these features in the input randomly. Note that for calculations, indexed vectors and structs you will not see the input printed out literally.
