	This .scss loop will create "margin helpers" and "padding helpers" for use in your web projects.
	It will generate several classes such as:

	.m-r-10 which gives margin-right 10 pixels.
	.m-r-15 gives MARGIN to the RIGHT 15 pixels.
	.m-t-15 gives MARGIN to the TOP 15 pixels and so on.

	.p-b-5 gives PADDING to the BOTTOM of 5 pixels
	.p-l-40 gives PADDING to the LEFT of 40 pixels
