// New Syntax, allows to optionally calculate on a different base value to counter compounding effect of rem's.

//
// Space delimited, if you want to delimit using comma's, wrap it in another pair of brackets
//
// rem-calc((10, 20, 30, 40px));
//
// Optionally call with a different base (eg: 8px) to calculate rem.
//
// rem-calc(16px 32px 48px, 8px);
//
// If you require to comma separate your list
//
// rem-calc((16px, 32px, 48), 8px);
