msm_curves: Curves file

The msm_curves class encodes one or more "curves" as a set of point indices.
Each curve is assumed to join the given points in the order supplied.
If the curve is not open, then it is assumed to be closed and the last point is connected to the first point.
The crvs file is a text file defining the curves in a fairly easy to read/edit way.
For example, face_68pts.crvs defines the curves on a 68 point face markup:
curves: { curve: { name: Chin open: true indices: { 0:14 } } curve: { name: LEyebrow open: false indices: { 15:20 } } curve: { name: REyebrow open: false indices: { 21:26 } } curve: { name: LEye open: false indices: { 27:30 } } curve: { name: REye open: false indices: { 32:35 } } curve: { name: Nose open: true indices: { 37:45 } } curve: { name: Nostrils open: true indices: { 46 47 } } curve: { name: OuterLips open: false indices: { 48:59 } } curve: { name: TopLip open: true indices: { 48 60 61 62 54 } } curve: { name: BottomLip open: true indices: { 54 63 64 65 48 } } } The elements of each curve are:

name: The following text (which must not include any whitespace) defines a name for the curve
open: true/false - Defines whether the curve is open or closed
indices: A list of integers defining the points to be connected. Ranges can be specified, such as 0:14 or 45:40 (for counting backwards) to indicate all integers in the given range.
