Title: Create _prefix-values.scss

Instead of using:
@include transition-property (transform);
@include transition-duration(1.0s);
@include transition-timing-function(ease-in);
@include transition-delay(0.5s);

Then this would help to create transition like so:
@include transition(transform 2s);

By using it inside prefixer mixin like so:

@mixin prefixer ($property, $value, $prefixes) {
@each $prefix in $prefixes {
@if $prefix == webkit {
@if $prefix-for-webkit {
-webkit-#{$property}: prefix-values($value, $prefix);
}
}
@else if $prefix == moz {
@if $prefix-for-mozilla {
-moz-#{$property}: prefix-values($value, $prefix);
}
}
@else if $prefix == ms {
@if $prefix-for-microsoft {
-ms-#{$property}: prefix-values($value, $prefix);
}
}
@else if $prefix == o {
@if $prefix-for-opera {
-o-#{$property}: prefix-values($value, $prefix);
}
}
@else if $prefix == spec {
@if $prefix-for-spec {
#{$property}: $value;
}
}
@else {
@warn "Unrecognized prefix: #{$prefix}";
}
}
}
